Patent ID: 7912106

Claim:
A surface-emitting photonic device comprising: a structure including: a two dimensionally periodic central square-lattice second order photonic crystal distributed feedback device (DFB) having a size that is tuned to emit diffraction limited outcoupled laser light having a predetermined wavelength along a propagation direction that is substantially normal to a plane of the DFB, and a square-lattice first order photonic crystal distributed Bragg reflector (DBR) coplanar with, adjacent to and entirely surrounding the DFB, such that a straight extension of any straight line that is coplanar with the DFB and which extends through a center of the DFB also extends from and to opposing portions of the DBR, the DBR including diffractive elements having geometries tuned independently of DFB size tuning and selected such that a bandgap of the DBR is maximized and centered around the predetermined wavelength of the emitted light; a substrate having an upper section on which the structure is entirely patterned and a lower section; and a semi-conductor quantum well laser interposed between the upper and lower sections of the substrate and having dimensions in a plane defined perpendicularly with respect to an emission direction of the emitted light that are substantially similar to like dimensions of the structure.
