Abstract:
An optoelectronic device employs a surface-trapped TM-polarized optical mode existing at a boundary between a distributed Bragg reflector (DBR) and a homogeneous medium, dielectric or air. The device contains a resonant optical cavity surrounded by two DBRs, and an additional DBR section on top supporting the surface-trapped mode. Selective chemical transformation, like selective oxidation, etching or alloy composition intermixing form a central core and a periphery having different vertical profiles of the refractive index. Therefore, the longitudinal VCSEL mode in the core is non-orthogonal to the surface-trapped mode in the periphery, and the two modes can be transformed into each other. Such transformation allows fabrication of a number of optoelectronic devices and systems like a single transverse mode VCSEL, an integrated optical circuit operating as an optical amplifier, an integrated optical circuit combining a VCSEL and a resonant cavity photodetector, etc.

Claim (Index 1):
An optoelectronic device comprising\n a) a first multilayer reflector bounded from the top by a homogeneous medium having a refractive index lower than the refractive index of the topmost layer of said first multilayer reflector,\n wherein said first multilayer reflector supports a first optical mode; \n wherein said first optical mode is a TM-polarized surface-trapped optical mode; \n wherein said first optical mode\n i) is localized at a boundary between said first multilayer reflector and said homogeneous medium, and \n ii) exhibits an evanescent decay in said homogeneous medium away from said boundary, and \n iii) exhibits an oscillatory decay in said first multilayer reflector away from said boundary; and \n \n b) a resonance cavity structure contiguous to said first multilayer reflector at the side opposite to said homogeneous medium;\n wherein said resonance cavity structure supports a second optical mode; \n wherein said second optical mode propagates in a vertical direction or in a direction tilted with respect to the vertical direction at an angle below five degrees in a semiconductor material; \n \n wherein said first optical mode and said second optical mode exist at a same wavelength of light; and \n wherein said first optical mode and said second optical mode are capable to transform into each other.
