We have seen in Chapter 6 that a conventional semiconductor laser does not emit light in a single longitudinal mode. In general, the mode closest to the gain peak is most intense, and a few percent of the output power is carried by other longitudinal modes lying close to the gain peak. ...
Distributed feedback (DFB) semiconductor lasers, especially those with gain-coupled (GC) mechanisms, are studied. AGaAlAs/GaAsmulti-quantum well GC-DFB laser with a loss grating is fabricated using MBE for the first time. A 1.3 μmInGaAsP/InPDFB laser with a loss grating and one with a ...
DFB Laser is an edge-emitting semiconductor light source. Compared to DBR Lasers, DFB Lasers are more stable & generate a clean single mode output. Inphenix’s DFB Laser has a simple & low-cost fabrication process and has many advantages
Distributed Feedback (DFB): Distributed Feedback (DFB) Diode Lasers are fixed wavelength single mode diode lasers. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height). The laser chip is grown by MOVPE of compound semiconductor material....

We find that a commonly-used distributed feedback laser diode (DFB-LD) can work as a graded-potential-signaling photonic neuron. Through theoretical and experimental demonstration, DFB-LDs are proved useful for three graded-potential-signaling-based neuromorphic processing applications of the pattern re...
The optical spectra of random fibre lasers have been conventionally reported to be of a smooth nature, a feature that has been commonly attributed to an underlying incoherent feedback mechanism. This is also in good agreement with the existing theoretical descriptions of the random fibre laser ...
A semiconductor laser that offers the tunability of an external-cavity system without its mechanical complexity is a Distributed Feed-Back (DFB) diode [4]. In a DFB diode, a Bragg grating is integrated into the active section of the semiconducto...
