英文摘要	An optical transmission circuit includes a light emitting device (10) having different temperature characteristics at low temperature and high temperature (e.g., a VCSEL (Vertical Cavity Surface Emitting Laser), differential switch transistors (M1, M2) for driving the light emitting device (10), the differential switch transistors having sources connected to each other and drains connected to the light emitting device (10) and a power supply, respectively, a bias current source (11) for causing a bias current to flow, a modulated current source (12) for causing a modulated current to flow, and a temperature compensation current source (20) for controlling currents of the bias current source (11) and the modulated current source (12) so as to compensate for both temperature characteristics at low temperature and temperature characteristics at high temperature of the light emitting device (10).
