TOPTICA’s DLC DFB pro lasers integrate both distributed-feedback (DFB) and distributed Bragg reflector (DBR) lasers. Available wavelengths include 633 nm and the entire range from 760 nm to 3500 nm.
Fluorescent polymer-based DFB lasers often incorporate the fluorescent polymer gain layer as the waveguide core, with a further polymer or silicon dioxide layer with an inscribed DFB grating forming the waveguide cladding.
3 wrz 2019 · Here we present the assembly of novel transparent all-polymer distributed feedback (DFB) lasers. Flexible and highly transparent cellulose diacetate (CdA) was employed as substrate on which...
Single-frequency, single-spatial mode distributed feedback (DFB) and distributed Bragg reflector (DBR) lasers have important applications in communication, spectroscopy, frequency conversion, atomic clocks and Doppler laser cooling.
A distributed-feedback laser (DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating.
alternative approach, which utilizes distributed-feedback (DFB) from a Bragg-type diffraction grating, provides a number of advantages while still utilizing a planar surface geometry.
Bragg reflectors (DBR),16 and distributed feedback (DFB) lasers.17 DFB lasers make use of periodic wavelength-scale nanostructures to backscatter photons within the plane of propagation.
