An optical mode converter is disclosed. The optical mode converter includes a substrate and a luminescent layer on the substrate. The luminescent layer includes an optical waveguide and an inclined mirror at an end of the optical waveguide. A light signal passes through the optical waveguide and is reflected by the inclined mirror to penetrate into the substrate. A method for manufacturing the optical mode converter is also disclosed.

Optical mode converter and method for manufacturing the same

A method for fabricating a waveguide construction is described and has steps of: providing a layered structure by: forming a first-type InGaAsP layer on a substrate, forming a first-type InP layer on the first-type InGaAsP layer, forming an active layer containing gallium on the first-type InP layer, forming a second-type InP layer on the active layer, and forming a second-type InGaAsP layer on the second-type InP layer; forming an SiOpatterned layer having SiOregions and at least one channel facing toward a desired direction and formed between the SiOregions on the second-type InGaAsP layer; and performing a rapid thermal annealing treatment on the layered structure formed with the SiOpatterned layer. The rapid thermal annealing treatment has a treating temperature between 720&#xb0; C. and 760&#xb0; C. and a treating time between 60 and 240 seconds.
