“…A semiconductor optical amplifier (SOA) interferometic wavelength converter has also been applied for single channel RZ-to-NRZ format conversion [4], but the scheme is relatively complex, and the SOA will introduce extra power consumption. Recently, a new compact scheme based on an optical nano-fiber ring resonator has been demonstrated for single channel RZ-to-NRZ format conversion [5]. However, such a nano-fiber ring resonator is very sensitive to the surrounding environment, making it unstable.…”

Abstract:We comprehensively analyze multiple WDM channels RZ-to-NRZ format conversion using a single microring resonator. The scheme relies on simultaneous suppression of the first order harmonic components in the spectra of all the RZ channels. An optimized silicon microring resonator with free spectral range of 100 GHz and Q value of 7900 is designed and fabricated for this purpose. Multi-channel RZ-to-NRZ format conversion is demonstrated experimentally at 50 Gbit/s for WDM channels with 200 GHz channel spacing using the fabricated device. Bit error rate (BER) measurements show very good conversion performances for the scheme.

“…The periodic notch filtering characteristic of the through transmission of a MRR can then be used to suppress the first order harmonic components of the spectrum, thus realizing RZ-to-NRZ format conversion. Residual amplitude ripples in the converted NRZ signal can be further reduced by an additional optical bandpass filter (OBPF) [5,7]. To effectively perform 640 Gbit/s RZ-to-NRZ format conversion, a MRR with FSR of 1280 GHz (corresponding to twice the bit rate of the signal [5]) is required.…”

“…In the past, significant efforts have been dedicated to on-off keying (OOK) RZ-to-NRZ conversion using nonlinear optical loop mirrors (NOLMs) [1], active injection locked lasers [2], or semiconductor optical amplifier (SOA) based devices [3,4] with relatively complex configurations. Single and multi-channel format conversions based on simple passive linear filter devices [5][6][7][8][9][10] have been demonstrated, however only applied to on-off keying modulation. On the other hand, because of its improved receiver sensitivity with balanced detection and superior transmission properties [11,12], differential phase shift keying (DPSK) has received special attention over the past decade.…”

Simultaneous RZ-OOK to NRZ-OOK and RZ-DPSK to NRZ-DPSK modulation format conversion in a single silicon microring resonator with free spectral range equal to twice the signal bit rate is experimentally demonstrated for the first time at 41.6 Gb/s. By utilizing an optimized custom-made microring resonator with high coupling coefficient followed by an optical bandpass filter with appropriate bandwidth, good conversion performances for both modulation formats are achieved according to the converted signals eye diagrams and bit-error-rate measurements.
