VCSEL Laser Diode Applications
by Electron Test Equipment | May 2, 2019 | Laser Diodes
What is VCSEL (VERTICAL CAVITY SURFACE EMITTING LASER)? VCSEL laser diodes are a semiconductor "vertical cavity surface emitting laser" diode that emits light in a cylindrical beam vertically from the surface of a fabricated wafer...
Laser Diode Reliability
by Electron Test Equipment | Jul 15, 2018 | Laser Diodes, Semiconductor Testing
The majority of semiconductor device reliability modeling is done using the exponential probability distribution model, which assumes the semiconductor has a constant failure rate and there is no wear-out mechanism. However, there are a number of factors which affect...
Laser Diode LIV
by Electron Test Equipment | Jun 26, 2018 | Laser Diodes
Laser diodes, the devices that illuminate telecom fiber-optic cables, require light-current-voltage (LIV) measurements during production. These measurements let you characterize a laser diode's light output and forward voltage as a function of input current....
What Is a Laser Diode
by Electron Test Equipment | Apr 26, 2018 | Laser Diodes
A laser diode falls under the category of optoelectronics which is a branch of electronics that deals with light-emitting and light-detecting devices. A laser diode is a special LED or IRED with a relatively large and flat P-N junction. How a Laser Diode Works Laser...
