Oscillator injection locking is an interesting subject; however, it seems to be a forgotten circuit concept that can be beneficial in some applications. Wow the engineering world with your unique ...

Optical injection locking is a technique by which the output of a semiconductor laser is stabilised and synchronised to that of an external “master” laser. This method harnesses the coherent ...

A direct modulation bandwidth of 66 GHz has been achieved from two daisy-chained VCSELs, and the principle could be scaled up to reach over 100 GHz. An international research team has shown that a ...
