چکیده
Wavelength-division-multiplexing (WDM) networks with wide channel grids and bandwidths are promising for low-cost, low-power optical interconnects. Wide-bandwidth, single-band (i.e., no free-spectral range) add-drop filters have been developed on silicon using anti-reflection contra-directional couplers with out-of-phase Bragg gratings. Using such filter components, we demonstrate a 4-channel, coarse-WDM demultiplexer with flat passbands of up to 13 nm and an ultra-compact size of 1.2 × 10(-3) mm(2).

Formation of a planar coarse wavelength-division multiplexer and demultiplexer with reflection volume phase gratings.
A compact configuration for a coarse wavelength-division multiplexer (CWDM) and a coarse wavelength-division demultiplexer (CWDDM) that are based on reflection volume phase gratings is formed. The design and calculated results for four-channel CWDM and CWDDM configurations in the region near 800 nm are presented. Theoretical predictions are experimentally verified with a four-channel CWDDM whos...
متن کاملTerahertz bandwidth photonic Hilbert transformers and implementations in ultra wideband single-sideband filters
Planar Bragg grating based photonic Hilbert transformers (PHTs) with THz bandwidths are proposed and practically demonstrated. An X-coupler, PHT, and a flat-top reflector are incorporated, demonstrating 2THz all-optical single-sideband filters. Devices are fabricated via a direct UV grating writing technique on a silica-on-silicon platform.

An ultra-compact (coupling length ~ 8.77 m) silicon polarization splitter and rotator is demonstrated based on a bent directional coupler. The peak TM-TE coupling efficiency reaches 96.6%. The crosstalk values are < -10 dB over a wavelength range of 40 nm.
متن کاملWidely bandwidth-tunable silicon filter with an unlimited free-spectral range.
Next-generation high-capacity optical networks require flexible allocation of spectrum resources, for which low-cost optical filters with an ultra-wide bandwidth tunability beyond 100 GHz are desired. We demonstrate an integrated band-pass filter with the bandwidth continuously tuned across 670 GHz (117-788 GHz) which, to the best of our knowledge, is the widest tuning span ever demonstrated on...
