Abstract
A reciprocating optical modulator (ROM) generates a millimeter-wave signal in good efficiency. Internal bias modulation on a ROM is reported, in this paper. Owing to reciprocating modulation in the ROM, the driving voltage required for amplitude modulation on a millimeter-wave signal is highly decreased. In this paper, a millimeterwave signal in the 52.8-GHz frequency band is amplitude-modulated with a low-voltage (2.0 V) baseband signal, where half-wave voltage of the modulator embedded in the ROM is 6.4 V.
