Wide bandwidth and high resolution planar filter array based on DBR-metasurface-DBR structures [PDF]
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 ...

Optically pumped DBR-free semiconductor disk lasers
We report high power distributed Bragg reflector (DBR)-free semiconductor disk lasers. With active regions lifted off and bonded to various transparent heatspreaders, the high thermal impedance and narrow bandwidth of DBRs are mitigated. For a strained InGaAs multi-quantum-well sample bonded to a single-crystalline chemical-vapor deposited diamond, a ...

51-nm Uniform-Intensity Tuning of Superstructure Grating Active-DBR Laser for 2-μm Wavelength Band
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 ...
