Single side-band modulation performance of a LiNbO sub(3) integrated modulator consisting of four-phase modulator waveguides

Single side-band (SSB) technologies are especially useful in optical fiber communication systems, such as higher density wavelength multiplexing and long-haul fiber transmission due to less nonlinear optical effects, because of the reduced optical power. This letter reports on the SSB modulation per...

Description
Summary:Single side-band (SSB) technologies are especially useful in optical fiber communication systems, such as higher density wavelength multiplexing and long-haul fiber transmission due to less nonlinear optical effects, because of the reduced optical power. This letter reports on the SSB modulation performance of a LiNbO sub(3) integrated modulator consisting of four phase modulator waveguides. Optical SSB modulation with suppressions of main carrier (-22.6 dB) and J sub(3) subcarrier (-18.4 dB) of a 10-GHz single-tone signal with a driving voltage of 6.3 V sub(p-p) was demonstrated. The total insertion loss was 10.6 dB
