Abstract—Modulation format conversion is useful when the signal
is transmitted through networks employing different modulation
formats. It is also expected to increase the spectral efficiency
and reduce power consumption in network nodes by applying alloptical
signal processing to the modulation format conversion. In
this paper, we propose an all-opticalmodulation format conversion
system between ON-OFF keying, quadrature phase-shift keying, and
8-ary quadrature amplitude modulation using optical nonlinear effects
in semiconductor optical amplifier and optical threshold device.
We also evaluate the conversion performances of the system
by numerical simulation in terms of optical signal-to-noise ratio,
optical signal power, and accumulated chromatic dispersion.
