| 英文摘要 | A semiconductor laser has been developed which is capable of efficiently transmitting a predetermined number of modes to an external fiber or waveguide. The laser includes an active gain region disposed in a laser cavity that is formed in a semiconductor material. A lens and a waveguide are also located in the laser cavity. The lens receives optical energy generated by the active gain region and directs this energy into one end of the waveguide. The waveguide transmits the optical energy from the laser to an external fiber or waveguide. The waveguide may be either a single mode waveguide or a multimode waveguide that selects a predetermined number of modes from among all the modes generated by the active region. If a single mode waveguide is employed, the output energy is composed of the fundamental frequency generated by the active region. If a multimode waveguide is employed, the output energy is composed of the predetermined modes selected by the waveguide. |
