S. Bigo et al., FUNDAMENTAL LIMITS OF ALL-OPTICAL NRZ-TO-SOLITON CONVERSION BY NONLINEAR-OPTICAL LOOP MIRRORS, Electronics Letters, 31(12), 1995, pp. 994-995
All-optical NRZ-to-RZ conversion through nonlinear optical loop mirror
s (NOLM) is analysed. By computing the time-bandwidth output character
istics, we investigate the dependence of the NOLM switching power and
control envelope on the chirp of the switched RZ pulses. The effect of
this chirp on further propagation in the soliton regime and related c
ontinuum generation is then analysed by an inverse-scattering transfor
m.
