Cyj. Chu et H. Ghafourishiraz, EFFECTS OF STRAY REFLECTIONS ON THE PERFORMANCE OF SEMICONDUCTOR-LASER AMPLIFIERS AS IN-LINE OPTICAL REPEATERS, Optics and Laser Technology, 26(6), 1994, pp. 403-407
The effects of stray reflections from the ends of optical fibres on th
e gain and spontaneous emission of a semiconductor laser amplifier hav
e been analysed. The transfer matrix method (TMM) has been applied to
give efficient solutions to the problem. The theoretical results show
that these stray reflections can seriously deteriorate the performance
of a single amplifier and can degrade the overall performance of a sy
stem incorporating a cascaded chain of amplifiers as in-line repeaters
.
