- Abstract
- A novel all-optical frequency up-converter utilizing four-wave mixing ( FWM) in a semiconductor optical amplifier ( SOA) was proposed and experimentally demonstrated. The frequency up-converter converted an optical intermediate frequency ( IF) signal ( f(IF) = 2.5 GHz) to an optical radio frequency ( RF) signal ( f(RF) = 35 and 40 GHz) through mixing with an optical local oscillator ( LO) signal ( f(LO) = 37.5 GHz). The up-converter showed positive conversion efficiency of 5.77 dB for the optical IF power of -22 dBm and the optical LO power of -13 dBm. This scheme showed broad bandwidths with respect to both LO and IF frequencies. The up-converter showed a phase noise of -84.5 dBc/Hz for the LO frequency of 37.5 GHz ( f(LO)) and the offset frequency of 10 kHz after the frequency up-conversion.
