A distributed feedback (DFB) laser array of twenty wavelengths with highly reflective and anti-
reflective (HR-AR) coated facets is both theoretically analyzed and experimentally validated …

Broad-area lasers (BA) are practical for producing high output power. However, under a
high current operation, high-order modes are easily excited, resulting in the broadened …

We report the latest development in high-speed directly modulated tunable laser based on

In this Letter, we design and realize a hybrid-cavity laser with single-or dual-mode lasing
states and study the nonlinear states of the laser under external optical feedback (EOF). The …

All-optical switching and multiple logic gates are experimentally demonstrated using
AlGaInAs/InP hybrid square-rectangular lasers. Controllable bistability induced by saturable …

We study modulation properties of two-element phased-array semiconductor lasers that can
be described by coupled mode theory. We consider four different waveguide structures and …

We propose and demonstrate a high-speed directly modulated laser based on a hybrid
deformed-square-FP coupled cavity (DFC), aiming for a compact-size low-cost light source …

We demonstrate a kind of ridge waveguide semiconductor laser with high-order sidewall
gratings around 1550 nm. The ridge waveguide with 11th-order sidewall gratings is …
