Gallium nitride (GaN) laser diodes (LDs) are considered for visible light communications
(VLC) in free space, underwater, and in plastic optical fibers (POFs). A review of recent …

Group-III-nitride optical devices are conventionally important for displays and solid-state
lighting, and recently have garnered much interest in the field of visible-light communication …

795 nm oxide-confined distributed feedback (DFB) lasers have been developed. The oxide-
confined structure is used to realize lateral optical and current confinement, and the first …

A novel, to the best of our knowledge, broad-area distributed feedback laser with high-order
surface curved gratings has been fabricated based on standard near ultraviolet lithography …

Single-frequency blue laser sources are of interest for an increasing number of emerging
applications but are still difficult to implement and expensive to fabricate and suffer from poor …

Single longitudinal mode continuous-wave operation of GaN-based distributed Bragg
reflector (DBR) laser diodes with 10th-order surface gratings is demonstrated. The DBR …

We demonstrate a compact and low-cost all-fiber-based locking setup for frequency-noise
suppression of a 420 nm external-cavity diode laser. Frequency noise reduction in the 100 …

Laser current and temperature control circuits have been developed for a distributed
feedback laser diode, which is applied as the light source of a tuneable diode laser …

We have developed a GaN-based distributed feedback laser diode (DFB-LD) with the
detuning of+ 5 nm to obtain a smaller temperature dependence of the threshold current. We …

This letter reports room-temperature electrically pumped narrow-linewidth GaN-on-Si laser
diodes. Unlike conventional distributed Bragg feedback laser diodes with hundreds of …
