HIGH GAIN SEMICONDUCTOR LASER AMPLIFIER PACKAGE |
摘要 |
A laser amplifier package comprises two laser amplifiers (1 and 2) coupled via two lenses (5 and 6) and an optical isolator (7). The first and second laser amplifiers may both be run as amplifiers to give an overall improved gain and reduced residual facet reflectivity. The first amplifier may be run as a pulse source as part of an LEC or gain switched DFB laser assembly. Pulses generated to be, or compressed to, near transform limited enable the output from the package to be optical solitons. The second laser amplifier may be switched to provide modulation.
