Modelocked distributed Bragg reflector laser
Electronics Letters, 1999 The fabrication and performance of a modelocked distributed Bragg reflector laser is described. The laser has a threshold current of 60 mA and differential efficiency of 0.05 mW/mA when coupled into a singlemode fibre. Modelocked pulses with 7 ps pulsewidth, with a time-bandwidth (/spl Delta/t/spl Delta//spl nu/) product of /spl sim/0.7, at /spl sim/5 ...

Polymer Distributed Bragg Reflectors for Vapor Sensing [PDF]
ACS Photonics, 2015 We establish a new strategy to achieve fast and responsive hybrid distributed Bragg reflectors for environmental vapor sensing. We fabricated easily processable zinc oxide–polystyrene nanocomposites to grow high quality multilayers with large gas permeability and dielectric contrast, which enable fast and sensitive detection of vapor analytes ...

Corrugated nanowires as distributed Bragg reflectors
Nano Express, 2022 Abstract Distributed Bragg reflectors (DBRs), comprised of periodic refractive index changes, are widely used in optoelectronic devices as resonators, filters and sensors. The heterostructures required for DBRs can be difficult to implement in nanostructures due to poor compositional control on the nanoscale.

Virtual cavity in distributed Bragg reflectors
Optics Express, 2018 We show theoretically and experimentally that distributed Bragg reflector (DBR) supports a surface electromagnetic wave exhibiting evanescent decay in the air and oscillatory decay in the DBR. The wave exists in TM polarization only. The field extension in the air may reach several wavelengths of light.

Selective Polymer Distributed Bragg Reflector Vapor Sensors [PDF]
Polymers, 2018 We report on Flory–Huggins photonic sensors for the selective detection of volatile organic compounds without the use of any chemical functionalization. For this purpose, we employed periodic multilayers made of inert cellulose acetate alternated to active polystyrene films whose free volume was modified with silanized ZnO nanoparticles.
