Wide bandwidth and high resolution planar filter array based on DBR-metasurface-DBR structures [PDF]
Optics Express, 2016 We propose and experimentally demonstrate a planar array of optical bandpass filters composed of low loss dielectric metasurface layers sandwiched between two distributed Bragg reflectors (DBRs). The two DBRs form a Fabry-P rot resonator whose center wavelength is controlled by the design of the transmissive metasurface layer which functions as a ...

A Widely Tunable Three-Section DBR Lasers for Multi-Species Gas Detection
Applied Sciences (Switzerland), 2021 We demonstrate a widely tunable distributed Bragg reflector (DBR) laser operating at 1.8-µm, in which the DBR section was butt-jointed InGaAsP (λ = 1.45 μm) material. Through current and temperature tuning, a widely tuning range of over 11 nm with a side

51-nm Uniform-Intensity Tuning of Superstructure Grating Active-DBR Laser for 2-μm Wavelength Band
IEEE Photonics Journal, 2022 To suppress the fluctuation of light intensity during wavelength tuning caused by carrier induced optical loss, we utilized a single quantum well (SQW) inserted into the bulk core layer of distributed Bragg reflectors (DBRs), called an active DBR ...
