Rfs. Ribeiro et al., FM RESPONSE OF QUANTUM-WELL LASERS TAKING INTO ACCOUNT CARRIER TRANSPORT EFFECTS, IEEE photonics technology letters, 7(8), 1995, pp. 857-859
The FM response of a single-frequency semiconductor laser is very impo
rtant for communication systems that use direct modulation of the lase
r injection current, A new rate equation for the optical phase in quan
tum-well lasers is proposed, and the corresponding PM response is deri
ved, It is shown that the separate-confinement-heterostructure can hav
e a significant effect on the laser performance. The theory is confirm
ed with experimental results.
