DIRECT COUPLING TYPE WAVELENGTH VARYING EXTERNAL RESONATOR LASER INCLUDING A HIGH FREQUENCY TRANSMISSION MEDIUM WHICH TRANSFERS A HIGH FREQUENCY SIGNAL TO A GAIN MEDIUM

摘要

PURPOSE: The direct coupling type wavelength varying external resonator laser is provided to a working speed by controlling an optical power capable of making the high speed operation.;CONSTITUTION: The wavelength varying external resonator laser (1000) comprises a gain medium (500), an optical waveguide structure (400), and the high frequency transmission media (600). The gain medium generates the optical signal according to an approved bias current. The optical waveguide structure comprises a mirror surface by combining with the gain medium, generates lasing inside the mirror facet when the approved bias current is over a threshold value. The high frequency transmission media comprises a dielectric body (610), a metallic thin film wire (620), and a matching resistance unit (630). The dielectric body controls the working speed of the optical signal by adding the high frequency signal in the approved bias current. The metallic thin film wire comprises a transmission line by combining with the dielectric body. The matching resistance unit performs a signal matching function by adding the resistance value of the gain medium.;COPYRIGHT KIPO 2013
