Tunable Reflection Bands and Defect Modes in One-Dimensional Tilted Photonic Crystal Structure
Photonic Crystal Structure Photonic Band Gap (PBG) Omnidirectional Reflector Tilted PC Structure De-fect Modes
2013/1/30
We show theoretically that range of reflection bands and defect modes inside the band gap can be tuned by using a one-dimensional tilted photonic crystal (TPC) structure. A TPC structure is similar to...
PCRR Based Bandpass Filter for C and L+U Bands of ITU-T G.694.2 CWDM Systems
Photonic Crystal Ring Resonator Photonic Bandgap CWDM, Bandpass Filter FDTD Method PWE Method
2013/1/30
A two Dimensional (2D) Photonic Crystal Ring Resonator (PCRR) based Bandpass Filter (BPF) is designed to cover C and L+U bands of Coarse Wavelength Division Multiplexing (CWDM) systems. It is devised ...
Synthesis of Chained Achromatic Layer Systems Forming Controlled Low Transmittance Bands
Thin Films Design Light Propagation
2013/1/30
The approach utilized in the design of achromatic periods formed of two layers a high-index and a low-index is developed by combining the first two periods together. These two periods are therefore re...

2013/5/24
Band-stop fiber-optic filters based on sampled long-pe-riod gratings (S-LPGs) have been fabricated and studied experimentally.Comparison between transmission spectra of the proposed S-LPGs and normal ...

Compact Multiwavelength Fiber Lasers L Bands
2015/7/16
We demonstrate multiwavelength CW lasers for S,C and L bands that emit more than 40 wavelengths simultaneously. We achieve a nominal channel spacing of 100 ± 10 GHz using post-fabrication correction b...
Far-Field Focus and Dispersionless Anticrossing Bands in Two-Dimensional Photonic Crystals
Far-Field Focus Dispersionless
2008/10/29
We review the simulation work for the far-field focus and dispersionless anticrossing bands in two-dimensional (2D) photonic crystals. In a two-dimensional photonic-crystal-based concave lens, the far...
Multiple omnidirectional reflection bands from half-wave layered periodic structures
thin films multilayers filters bandgaps 1D photonic crystals
2011/4/26
The paper is concerned with one-dimensional multilayers that exhibit multiple bands of omnidirectional reflection, which means complete reflection regardless of incidence angle and polarization. The t...
