Patent ID: 7283448

Claim:
An integrated optical pickup comprising: a light source; a main photo-detector, which receives light emitted from the light source and reflected from an optical information storage medium; a light-collecting and optical path separating member disposed on a portion of a first wafer, and operable to focus light emitted from the light source on the optical information storage medium and separates an optical path of light incident on the optical information storage medium from an optical path of light reflected from the optical information storage medium; and an optical bench disposed on a portion of a second wafer and coupled to the light-collecting and optical path separating member, an optical path being formed between the light source and the main photo-detector, and the light-collecting and optical path separating member; wherein the optical bench includes a first lateral side part having a first surface that reflects the light emitted from the light source toward the light-collecting and optical path separating member; and the light source is disposed on a bottom part of the optical bench, and the main photo-detector is disposed on either the bottom part of the optical bench or a second lateral side part opposite to the first lateral side part.
