Inquiry about Vertical Cavity Surface Emitting Laser DML
A VCSEL (Vertical cavity surface emitting laser) is a type of diode laser that emits a near-Gaussian beam perpendicular to the top surface. In data communication, large data rates combined with excellent energy efficiency and temperature stability have been achieved based on advanced device design and modulation formats. The laser resonator consists of a thin active region with one or several very thin (quantum well) amplifying layers sandwiched between two distributed Bragg reflectors (DBRs). Vertical-cavity surface-emitting lasers (VCSELs) are the ideal optical sources for data communication and sensing. Despite their low manufacturing costs, diffraction-limited, narrow-band emission and excellent modulation capability, VCSELs were only used for optical data transmission.

Purchase DFB Distributed Feedback Laser LPO
Explore 26 top manufacturers and suppliers of Distributed Feedback Lasers in our comprehensive photonics buyers' guide. A distributed feedback (DFB) laser is a laser where the optical resonator is formed not by discrete mirrors at the ends (as in Fabry–Pérot laser diodes) but by a periodic variation of the refractive index or gain (a Bragg grating) distributed throughout the active medium. Their key features relative to other semiconductor lasers are their single longitudinal mode (single frequency) emission profile, their high stability and their wavelength tunability. The frequency-selective element – a Bragg grating – is integrated into the chip itself and ensures continuous single-frequency operation.
