ABSTRACT:
An optical semiconductor device includes a plurality of light emitting elements, such as a semiconductor laser device, on the same semiconductor substrate, or an optical semiconductor device includes a light emitting element and light receiving element on the same semiconductor substrate, or an optical semiconductor device includes a light emitting element and electrical circuit element on the same semiconductor substrate. A light absorbing layer, which prevents the leakage of light from the light emitting element, even when it is reflected at the electrodes, etc., from reaching the other light emitting element or light receiving element or electrical circuit element, is formed on the semiconductor substrate.
