Abstract:
A surface-emitting quantum cascade laser of an embodiment comprises a substrate, an active layer, and a photonic crystal layer. The active layer has optical nonlinearity, and is capable of emitting a first and a second infrared laser light. The photonic crystal layer includes a first and a second region. The rectangular grating of the first region is orthogonal to the rectangular grating of the second region. The first infrared laser light has a wavelength corresponding to a maximum gain outside a first photonic bandgap in a direction parallel to a first side of two sides constituting the rectangular grating. The second infrared laser light has a wavelength corresponding to a maximum gain outside a second photonic bandgap in a direction parallel to a second side of the two sides of the rectangular grating.

Claim (Index 8):
The laser according to  claim 1 , wherein\n the rectangular grating is composed of pit parts having a lower refractive index than the photonic crystal layer therearound, length of each pit part in the direction parallel to the first side is larger than length parallel to the second side, and the each pit part is shaped to be asymmetric with respect to lines passing through a barycenter of the each pit part and being parallel to the first side and the second side, respectively.
