Fundamentals of Optical Waveguides is an essential resource for any researcher, professional or student involved in optics and communications engineering. Any reader interested in designing or ...actively working with optical devices must have a firm grasp of the principles of lightwave propagation. Katsunari Okamoto has presented this difficult technology clearly and concisely with several illustrations and equations. Optical theory encompassed in this reference includes coupled mode theory, nonlinear optical effects, finite element method, beam propagation method, staircase concatenation method, along with several central theorems and formulas. Since the publication of the well-received first edition of this book, planar lightwave circuits and photonic crystal fibers have fully matured. With this second edition the advances of these fibers along with other improvements on existing optical technologies are completely detailed. This comprehensive volume enables readers to fully analyze, design and simulate optical atmospheres. * Exceptional new chapter on Arrayed-Waveguide Grating (AWG) * In-depth discussion of Photonic Crystal Fibers (PCFs) * Thorough explanation of Multimode Interference Devices (MMI) * Full coverage of polarization Mode Dispersion (PMD)

From its inception nearly 30 years ago, the optical subdiscipline now referred to as nonimaging optics, has experienced dramatic growth. The term nonimaging optics is concerned with applications ...where imaging formation is not important but where effective and efficient collection, concentration, transport and distribution of light energy is, ie. solar energy conversion, signal detection, illumination optics, measurement and testing. This book will incorporate the substantial developments of the past decade in this field. Those that will benefit from this book include advanced undergraduate and graduate students, workers in illumination optics and signal detection, members of OSA, SPIE, APS, and solar energy groups (ASES and ISES) who work in nonimaging optics.
Optika geometri merupakah salah satu disiplin ilmu yang mempelajari perambatan sinar. Penelitian bertujuan untuk mengetahui kesalahan mahasiswa dalam melakukan representasi visual pada penyelesaian ...soal optika geometri. Metode penelitian menggunakan ex post facto. Subjek penelitian mahasiswa tadris biologi berjumlah 146 yang telah mendapatkan materi optika geometri pada tingkat sekolah menengah atas. Instrumen soal representasi visual terdiri dari 8 soal tes kinerja. Hasil penelitian menunjukkan kesalahan representasi visual yang dilakukan mahasiswa disebabkan oleh 1) mahasiswa tidak memahami konsep pembiasan dan pemantulan sinar pada lensa, 2) mahasiswa tidak menguasai konsep tentang sinar istimewa pada diagram pembentukan bayangan lensa dan alat optik, 3) mahasiswa tidak memahami hukum snellius dalam memecahkan persoalan pemantulan sempurna, perambatan sinar dari medium yang lebih rapat ke medium yang kurang rapat, perambatan sinar dari medium kurang rapat ke medium lebih rapat 4) mahasiswa tidak membedakan simbol dalam melakukan representasi visual.
Since the 3rd edition appeared, a fast evolution of the field has occurred. The fourth edition of this classic work provides an up-to-date account of the nonlinear phenomena occurring inside optical ...fibers. The contents include such important topics as self- and cross-phase modulation, stimulated Raman and Brillouin scattering, four-wave mixing, modulation instability, and optical solitons. Many new figures have been added to help illustrate the concepts discussed in the book.New to this edition are chapters on highly nonlinear fibers and and the novel nonlinear effects that have been observed in these fibers since 2000. Such a chapter should be of interest to people in the field of new wavelengths generation, which has potential application in medical diagnosis and treatments, spectroscopy, new wavelength lasers and light sources, etc.
Prilikom proučavanja valne prirode svijetlosti u srednjoj školi bilo bi korisno da škola posjeduje spektrometar kako bi učenici mogli vidjeti primjer upotrebe difrakcije svijetlosti za određivanje ...valnih duljina izvora svijetlosti. Također bi na vježbama učenici mogli proučavati od kojih valnih duljina se sastoje različiti izvori svijetlosti, te u određenim slučajevima određivati i kemijske elemente sadržane u izvoru svijetlosti. Kako se cijena komercijalnog spektrometra kreće oko 1000$, odlučili smo sami pokušati izraditi digitalni spektrometar uz pomoć mikroupravljača i linearnog CCD senzora. U samoj izradi, osim autora, dijelom su sudjelovali i učenici četvrtog razreda, smjera tehničara za računalstvo, u sklopu predmeta „Mikroupravljači“. Rezultat izrade spektrometra bio je uspješan, za cijenu od 20$ uspjeli smo napraviti digitalni spektrometar za spektar od 350 nm do 800 nm, preciznosti i rezolucije oko 1 nm, koji se vrlo dobro uklopio u nastavu fizike. U radu je opisana konstrukcija i kalibracija spektrometra, programski alati i komponente potrebne za izradu spektrometra, te najvažnije, primjena i upotreba ovako izrađenog spektrometra u nastavi fizike u srednjoj školi.
Presents readers with the basic science, technology, and applications for every type of adaptive lensAn adaptive lens is a lens whose shape has been changed to a different focal length by an external ...stimulus such as pressure, electric field, magnetic field, or temperature. Introduction to Adaptive Lensesis the first book ever to address all of the fundamental operation principles, device characteristics, and potential applications of various types of adaptive lenses.This comprehensive book covers basic material properties, device structures and performance, image processing and zooming, optical communications, and biomedical imaging. Readers will find homework problems and solutions included at the end of each chapter—and based on the described device structures, they will have the knowledge to fabricate adaptive lenses for practical applications or develop new adaptive devices or concepts for advanced investigation.Introduction to Adaptive Lensesincludes chapters on:Optical lensesElastomeric membrane lensesElectro-wetting lensesDielectrophoretic lensesMechanical-wetting lensesLiquid crystal lensesThis is an important reference for optical engineers, research scientists, graduate students, and undergraduate seniors.
The purpose of this study is to determine to what extent students' problem solving skill on geometric optical topic. The method used was survey on 34 students of XI graders at SMA Negeri 9 Malang who ...have obtained optical geometry lesson. The average score of problem solving skill of students was 61,12, with the highest score was 184 and the lowest score was 34. The result of the research shows that students problem solving ability in the novice category is bigger than expert category,thus it needs to implement learning which improves students problem solving ability. Abstrak: Tujuan dari penelitian ini adalah untuk mengetahui sejauh mana kemampaun pemecahan masalah siswa pada materi optika geometri. Metode yang digunakan dengan survei pada 34 siswa kelas XI SMA Negeri 9 Malang yang telah memperoleh pelajaran optika geometri. Nilai rata-rata kemampuan pemecahan masalah siswa sebesar 61,12 dengan nilai tertinggi adalah 184 dan nilai terendah 34. Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah siswa dalam kategori novice lebih besar daripada kategori expert, sehingga perlu diterapan pembelajaran untuk meningkatkan kemampuan pemecahan masalah siswa.
