Patent ID: 7266135

Claim:
A method for forming a resonant reflector on a top layer of an optoelectronic device, the method comprising: depositing a first material layer on the top layer of the optoelectronic device, the first material layer having a first refractive index and a thickness of about an odd multiple of a quarter of a wavelength to which the optoelectronic device is tuned, wherein the first material layer comprises a top mirror layer of a DBR mirror; creating at least one patterned region that extends at least partially into the first material layer, the thickness of the first material layer being reduced in the at least one patterned region; filling, partially at least, at least one selected patterned region with a second material having a second refractive index, one of the first and second refractive indices being greater than the other of the first and second refractive indices; and depositing a third layer immediately adjacent the first material layer, the third layer having a refractive index greater than the refractive index of the first material layer.
