A varying-width recess gate structure having a varying-width recess formed in a semiconductor device can sufficiently increase the channel length of the transistor having a gate formed in the varying-width recess, thereby effectively reducing the current leakage and improving the refresh characteristics. In the method of manufacturing the recess gate structure, etching is performed twice or more, so as to form a gate recess having varying width in the substrate, and a gate is formed in the gate recess.

Provided is an optical deflector for deflecting radiation beams. The optical deflector includes: a peripheral region having a first effective refractive index; and a deflection pattern region having a predetermined shape and a second effective refractive index, wherein the second effective refractive index differs from the first effective refractive index. Here, due to the deflection pattern region having the predetermined shape, the radiation beams are deflected in a direction starting from a certain point. By using the optical deflector, the locus of a light source can be designed in one of various forms, such as a straight line, a circle, an ellipse, or a parabola.

Provided is a tunable external cavity laser diode using a variable optical deflector wherein the variable optical deflector, in which a refractive index varies according to an electrical signal, is arranged in a triangular shape between a concave diffraction grating and a reflective mirror. Since a resonant frequency is changed using the electrical signal rather than the mechanical movement, the stable operation and continuous high-speed tenability may be enabled. In addition, when the tunable external cavity laser diode according to the present invention is implemented in an InP/InGaAsP/InP slab waveguide, a variable time determined by the carrier lifetime may be reduced to several nanoseconds or less, the miniaturization is enabled, and the manufacturing costs are significantly reduced due to the process simplification. Moreover, when the concave diffraction grating is designed based on a silica (or polymer) based slab waveguide, the fabrication may be performed even by a lithography process having low resolution, thereby enhancing reproducibility and uniformity of the diffraction grating, and accordingly reducing the manufacturing costs.

The present invention provides an opto-electronic device with an integrated light deflector comprises: a passive optical waveguide having a lower cladding layer, a core, and an upper cladding layer to guide and transmit optical signals; and a light deflector formed by patterning the upper cladding layer in a predetermined shape at an upper portion of the passive optical waveguide, wherein a refractive index of the core under the predetermined shape is modified to deflect a light beam by applying a current or an electrical field to the light deflector. According to the present invention, it is possible to provide an opto-electronic device with an integrated light deflector capable of deflecting the light propagation direction without necessity of a complicated external driving circuitry.
