Long Wavelength VCSEL-by-VCSEL Optical Injection Locking [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2009 Vertical-cavity surface-emitting laser (VCSEL)-by-VCSEL optical injection locking to obtain high cutoff frequencies of 1.3-mum VCSELs is demonstrated. A detailed physical explanation of the underlying mechanism is presented. VCSELs from the same wafer have been used in a master-follower configuration.
