Abstract

Light from discrete red, blue, and green lasers are combined into a single output using a planar lightwave circuit (PLC). In some embodiments some light from an output of the PLC is reflected back to the lasers, and in some embodiments the reflected light is primarily of one of the red, green, or blue wavelengths. In some embodiments multiple lasers of slightly differing wavelengths are provided as light sources for some or all of the red, blue, and green light.
