An optical transmitter according to the present disclosure is an optical transmitter that includes: an RF line configured to supply an electric signal; an EA-DFB laser chip configured to convert the electric signal to an optical signal and including an LD configured to oscillate laser light to be a source of signal light to be emitted, an EA modulator configured to perform intensity modulation on the laser light, an SOA configured to amplify the signal light subjected to the intensity modulation, and a waveguide configured to guide the laser light and the signal light; a first parallel-plate capacitor for removing noise in an electric current to be supplied to the LD, a second parallel-plate capacitor for removing noise in an electric current to be supplied to the SOA, and multiple wires electrically connecting the elements, the second parallel-plate capacitor is arranged adjacent to the SOA and the RF line.
An optical transmitter using an assembly of a distributed feedback laser integrated with electro-absorption (EA-DFB laser), the optical transmitter comprising:
