P. Correc et al., ON THE THERMAL CONTRIBUTION TO THE FM RESPONSE OF DFB LASERS - THEORYAND EXPERIMENT, IEEE journal of quantum electronics, 30(11), 1994, pp. 2485-2490
Laser diodes exhibiting a dip-free FM response will be key devices for
future coherent FSK systems. We studied (both theoretically and exper
imentally) the thermal contribution to the FM response of a laser. It
turns out that the agreement is good enough to validate the Fourier tr
ansform approach. This enables us to propose schemes to reduce the the
rmal FM response: decrease the heat generated in the laser and/or its
thermal resistance by episide-down mounting.
