A modified rate equation model is established to elucidate the optical injection induced gain-switching and NRZ-to-RZ data conversion in the VCSEL. The peak-to-peak frequency chirp of the VCSEL based NRZ-to-RZ is 4.5 GHz associated with a reduced frequency chirp rate of 178 MHz/ps at input optical NRZ power of -21 dBm, which is almost decreasing by a factor of 1/3 comparing with chirp on the SOA based NRZ-to-RZ converter reported previously. The power penalty of the BER measured back-to-back is about 2 dB from 1 Gbit/s to 2.5 Gbit/s. © 2008 Optical Society of America.Analog to digital conversion; Bit error rate; Mathematical models; Optical gain; Wavelength; All-optical NRZ-to-PRZ converter; Frequency chirp rate; Optical injection; Rate equation model; Surface emitting lasers; article; computer network; computer simulation; diode laser; equipment; equipment design; instrumentation; signal processing; telecommunication; theoretical model; Computer Communication Networks; Computer Simulation; Equipment Design; Equipment Failure Analysis; Lasers, Semiconductor; Models, Theoretical; Signal Processing, Computer-Assisted; Telecommunications[SDGs]SDG7journal article10.1364/OE.16.0048382-s2.0-41649119168
