H. Chida et al., 25-100-DEGREES-C AUTOMATIC POWER-CONTROL FREE 600MBIT S MODULATION OF0.98-MU-M INGAAS/ALGAAS LASER FOR HIGH-SPEED DATA LINK/, Electronics Letters, 31(23), 1995, pp. 2006-2008
Highly stable, temperature insensitive laser diodes emitting at 0.98 m
u m have bren developed. A low 2.3 mA threshold current was achieved a
t 25 degrees C, and a high 0.48 W/A slope efficiency was achieved at 1
00 degrees C by optimising the waveguide structure, cavity length and
front mirror reflectance. The power attentuation ratio from 25 to 100
degrees C was as low as -0.8 dB under a 30 mA drive current. The eye-o
pening ratio was >94% up to 100 degrees C under automatic power contro
l (APC) free 600 Mbit/s modulation and 2.3 mA DC bias.
