Latest Patents

Lau's latest patents include a superluminescent diode and a single mode laser. The superluminescent diode features a buried heterostructure window device with an elongated layer of gain medium surrounded by a lower index of refraction medium. This design effectively guides light along the length of the gain medium. A window and an antireflective layer are deposited on the output end of the gain layer to minimize reflections. The device is electrically pumped, with a portion of the gain medium nearer the output end being activated, while the unpumped end absorbs light traveling along the length of the gain medium. This configuration inhibits reflection from the remote end of the gain medium. When pumped at moderate power levels, the device produces strong superluminescent output. When pumped above the lasing threshold, it achieves a single mode laser with side band power at least 20 dB below the principal oscillation mode. The process of 'burning through' the unpumped absorbing portion can be inhibited by extracting current carriers from that section of the medium.
