Abstract
A laser diode assembly capable of guiding a laser beam to a predetermined direction by utilizing a reflecting surface which has an arbitrary angle with respect to a sub-mount. The assembly includes a first unit, a second unit, and a laser diode. The first unit has a first surface and a mounting surface inclined to the first surface. The second unit is made of a semiconductor substrate and is on the first unit. The second unit has a second surface and a reflecting surface that coincides with a (111) surface of the semiconductor substrate inclined to the second surface. The laser diode is on the second surface and irradiates a laser beam to the reflecting surface along a direction parallel to the second surface. The second unit is on the first unit in a manner that the second surface is disposed parallel to the mounting surface. thereby realizing an inclined angle of the reflecting surface with respect to the first surface of 45 degrees.
