Patent ID: 7339965

Claim:
A semiconductor optoelectronic device comprising: a) a cavity; b) at least one multilayered interference reflector; c) at least one p-n junction element; and d) a substrate; wherein the refractive index of the cavity is lower than a square root of a weighted average of a square of the refractive index of the multilayered interference reflector; wherein a resonant optical mode, having a first wavelength and propagating at a first tilt angle has a first absolute value of the electric field strength at the p-n junction element and a first value of the leakage losses out of the cavity into the substrate; wherein optical modes at a different wavelength than the first wavelength or propagating at a different angle than the first angle have a second absolute value of the electric field strength at the p-n junction element smaller than the first absolute value; wherein the tilt angle is defined as an angle between a direction of propagation of light within the p-n junction element and a direction normal to the lateral plane; and wherein the second absolute value of the electric field strength at the p-n junction element is smaller than the first absolute value by a factor greater than 3.
