Abstract:
Higher power tunable lasers are feasible using photonics integrated circuit based external cavity laser configurations by using multiple RSOAs inside a single cavity to provide multiple on-chip coherent optical output at the same wavelength. The total collective output power in various output branches potentially adds up being higher than what commercial lasers can provide. Using multiple RSOA increases and distributes the number of gain materials, which keeps them in a linear regime and avoids available gain saturation, which thereby removes gain saturation limitation in optical amplifications.

Claim (Index 1):
An external cavity laser device comprising:\n a first gain medium for generating light; a first reflector at one end of the first gain medium for reflecting light back through the first gain medium; a second gain medium for generating light; a second reflector at one end of the second gain medium for reflecting light back through the second gain medium; and a first coupler including a first input/output port optically coupled to the first gain medium, a second input/output port optically coupled to the second gain medium, and first and second output ports for outputting laser light at a selected wavelength range; whereby light travelling from the first gain medium via the first input/output port is split into first and second portions by the first coupler, with the first portion passing to the second gain medium, and the second portion passing to the first output port as a first output beam, and whereby light travelling from the second gain medium via the second input/output port is split into third and fourth portions by the first coupler, with the third portion passing to the first gain medium, and the fourth portion passing to the second output port as a second output beam.
