Abstract

The relation of spanned optical spectrum and modulation intensity in a phase modulator is calculated in this paper. The frequency spectrum of 0.6328 μm light driven by 2.45 GHz microwave at 1 W power is analyzed and observed. Finally, with a grating spectrometer, the 0.13 nm spectrum width at 16 W microwave power is measured. The two measured results are in good agreements.
