Patent ID: 6881984

Claim:
An optical transmission module comprising: a resonant-cavity light-emitting diode, said resonant-cavity light-emitting diode including: a substrate having a first main surface and a second main surface which are substantially parallel to each other, a first semiconductor distributed Bragg reflector mirror layer formed on said first main surface of said substrate, a semiconductor light-emitting layer formed over said first semiconductor distributed Bragg reflector mirror layer, a second semiconductor distributed Bragg reflector mirror layer formed over said semiconductor light-emitting layer, a light extraction section which is formed on said second semiconductor distributed Bragg reflector mirror layer and has an opening to extract light from said semiconductor light-emitting layer, a first electrode formed around said light extraction section on said second semiconductor distributed Bragg reflector mirror layer, a second electrode formed on said second main surface of said substrate, and a reflector portion provided on an inner wall of a groove, said groove being formed by removing portions of said first semiconductor distributed Bragg reflector mirror layer, said semiconductor light-emitting layer and said second semiconductor distributed Bragg reflector mirror layer which lie in a peripheral portion of said first electrode and formed to penetrate through each of said semiconductor light-emitting layer reflector mirror layer and said second semiconductor distributed Bragg reflector layer and reach said first semiconductor distributed Bragg reflector mirror layer, said reflector portion being formed to reflect part of light emitted from said semiconductor light-emitting layer into said groove; and an optical fiber on which light from said light extraction section and groove of said resonant-cavity light-emitting diode is incident.
