WASHINGTON, D.C., February 14, 2017 -- Vertical-cavity surface-emitting lasers (VCSELs) are small, semiconductor-based lasers that emit optical beams from their top surface, and one of their main ...
Alight Technologies is tackling the need for powerful long-wavelength, singlemode VCSELs by marrying its photonic-bandgap technology with Infineon's dilute-nitride platform. Dan Birkedal and Dirk ...
Fabricating microlenses directly on to the top of a VCSEL's gain structure creates a versatile single-mode source. A tunable single-mode VCSEL that uses an intracavity polymer microlens could be ideal ...
Semiconductor lasers are the most widely used lasers due to their compact size, high efficiency, low cost and wide spectra. But they suffer low output power and low beam quality—two specifications ...
In collaboration with Sony, the National Institute of Information and Communications Technology developed an electrically driven VCSEL that operates at 1,550 nm. This is the standard wavelength used ...
DUBLIN--(BUSINESS WIRE)--The "VCSEL Market by Type (Single-Mode, Multimode), Material (GaAs, InP, Others), Wavelength, Application (Sensing, Data Communication ...
Figure 1. Schematic of a tunable microlaser based on phase-change perovskite gain medium, sandwiched between Au mirror and DBR reflector sitting on a quartz glass substrate, pumped by blue-violet ...
Optical spectrometers with a high resolution, high speed triggering response as well as short integration time specifications are required to test VCSELs by manufacturers of these devices and device ...
The need to expand reach in metro networking equipment designs has never been more important. With service providers trying to deliver more services with existing equipment, designers are being forced ...
