Abstract
Provided is an optical device including a radio frequency (RF) signal source configured to electrically provide an RF signal, a first diode configured to operate as a laser diode (LD) or an electro-absorption modulator (EAM) in response to the RF signal, a second diode configured to share an N region of the first diode, be serially connected to the first diode, and have a P region connected to a ground to operate as a capacitor for series push-pull operation with the first diode, and a resistor connected between the N region and the ground.
