Abstract
Nonlinear distortion introduced by the optical transmitter using a direct modulation of laser diode(LD) and an indirect modulation of optical modulator can limit considerably the performance of analog optical link system such as subcarrier multiplexing system. In this paper, we have compensated the nonlinear distortion of LD and optical modulator using electrical predistorter. In the case of LD, two-tone experiments using 877.5 MHz and 882.5 MHz have shown reduction of 19 dB in third-order intermodulation product(IMP$_3$). And in the case of optical modulator, we have achieved nearly 21 dB reduction in IMP3 through two-tone experiments using 1.8975 GHz and 1.9025 GHz. The spurious free dynamic ranges of LD and optical modulator are also improved by 5 dB/Hz$^{2}$ 3/ and 7 dB/Hz$^{2}$ 3/, respectively.
