Title:
COMBINED SINGLE-FREQUENCY LASER AND LINEAR AMPLIFIER
Document Type and Number:
WIPO Patent Application WO2000072414
Kind Code:
A3
Abstract:
A semiconductor laser device includes a substrate having on a surface thereof a semiconductor diode laser portion and a linear amplifier portion. Each of the laser portion and amplifier portion has a waveguide layer with the waveguide layers being in alignment. The laser portion is of a structure which permits it to generate radiation and emit the radiation from one end. The amplifier has an end that receives the radiation from the laser portion, and another end which emits the radiation after the radiation is amplified. The device emits FM radiation but not IM radiation.
