Abstract
An optical semiconductor device includes a first set of lead frames having a first set of element mounting beds, a second set of lead frames having a second set of element mounting beds, which are arranged substantially on a same plane as the first set of element mounting beds. A light-emitting element is mounted on one of the first set of element mounting beds and having a pair of electrodes connected to the first set of lead frames respectively. A light-receiving element is arranged at a position facing to the light-emitting element and having a pair of electrodes connected to the second set of lead frames respectively. A supporting means is mounted on the second set of element mounting beds for supporting the light-receiving element at the position facing to the light-emitting element and for receiving a light emitted from the light-emitting element.
