Monolithically integrated multi-wavelength VCSEL arrays using high-contrast gratings.
We propose a novel design for multi-wavelength arrays of vertical cavity surface-emitting lasers (VCSELs) using high-contrast gratings (HCGs) as top mirrors. A range of VCSEL cavity wavelengths in excess of 100 nm is predicted by modifying only the period and duty-cycle of the high-contrast gratings, while leaving the epitaxial layer thickness unchanged. VCSEL arrays fabricated with this novel ...
متن کاملMonolithically integrated 40GHz pulse source with >40nm wavelength tuning range
A monolithically integrated device combines 40 GHz dual mode-locked operation with the wide tuning range (>40nm) of sampled-grating DBR lasers, while further being integrated to an SOA and a potentially high-speed modulator. OCIS codes: (250.5300) Photonic integrated devices; (140.3600) Lasers, tunable; (140.4050) Mode-locked lasers
متن کاملLiquid-crystal blazed-grating beam deflector.
A transmission-type nonmechanical multiple-angle beam-steering device that uses liquid-crystal blazed grating has been developed. Sixteen steering angles with a contrast ratio of 18 has been demonstrated. A detailed analysis of the liquid-crystal and poly(methyl methacrylate) blazed-grating deflector was carried out to provide guidance during the deflector's development. A manufacturing offset ...
متن کاملMonolithically Integrated Wavelength-Routing Switch Using Tunable Wavelength Converters with Double-Ring-Resonator Tunable Lasers
We present an 8 × 8 wavelength-routing switch (WRS) that monolithically integrates tunable wavelength converters (TWCs) and an 8 × 8 arrayed-waveguide grating. The TWC consists of a double-ringresonator tunable laser (DRR TL) allowing rapid and stable switching and a semiconductor-optical-amplifier-based optical gate. Two different types of dry-etched mirrors form the laser cavity of the DRR TL...
متن کاملFlexible and Wavelength-Selective MoS2 Phototransistors with Monolithically Integrated Transmission Color Filters
Color-selective or wavelength-tunable capability is a crucial feature for two-dimensional (2-D) semiconducting material-based image sensor applications. Here, we report on flexible and wavelength-selective molybdenum disulfide (MoS2) phototransistors using monolithically integrated transmission Fabry-Perot (F-P) cavity filters. The fabricated multilayer MoS2 phototransistors on a polyarylate su...
