Optical frequency-modulated continuous-wave (FMCW) reflectometry is a ranging technique
that allows for high-resolution distance measurements over long ranges. Similarly, swept …

We demonstrate a compact, robust, and stable terahertz source based on a novel two
section digital distributed feedback laser diode and plasmonic photomixer. Terahertz wave …

A single-mode laser structure suitable for photonic integration is presented. The laser can be
fabricated by standard photolithography without any regrowth steps. Through optimization, a …

We report on the continuous-wave, room-temperature operation of a distributed-feedback
laser diode (DFB-LD) with high-order notched gratings. The design, fabrication, and …

A sequence of partially reflective slots etched into an active ridge waveguide of a 1.5 mum
laser structure is found to provide sufficient reflection for lasing. Mirrors based on these …

Ex-facet, free-running low linewidth (~ 100 kHz), single mode laser emission is
demonstrated using low cost, regrowth-free ridge waveguide Discrete Mode Fabry Pérot …

This paper presents a tunable single mode Dual-mirror Slotted Fabry Pérot (DSFP) laser
with near 60 nm tuning of the wavelengths between 1530 nm to 1590 nm. The laser modes …

A single-mode laser structure based on slots suitable for monolithic photonic integration is
presented. The laser can be fabricated by photolithography without any regrowth steps …

Laser diodes based on Gallium Nitride (GaN) are useful devices in a wide range of
applications including atomic spectroscopy, data storage and optical communications. To …

A novel concept for an arrayed-waveguide-grating (AWG)-based fast tunable laser is
presented. It is fabricated in the InP–InGaAsP monolithic integration technology. Laser …
