Patent ID: 11164990

Abstract:
[Object] To provide an optical device and a display apparatus capable of decreasing a waveguide loss, inhibiting a laser oscillation, and achieving a high-output.[Solving Means] An optical device includes a first electrode layer, a first conduction type layer, a second conduction type layer, an active layer, and a second electrode layer. The first conduction type layer includes a current injection region formed by the first electrode layer and a current non-injection region. A waveguide structure included in the first conduction type layer, the active layer, and the second conduction type layer includes a first region and a second region. The first region has a first waveguide that is the current injection region and the current non-injection region and having a first refractive index difference. The second region has a second waveguide arranged to be extended from the first waveguide to the first end and has a second refractive index difference greater than the first refractive index difference. The second waveguide has a reflection structure that reflects light entered from the first waveguide and slopes an optical axis and a taper structure that decreases a size of a beam spot of light entered from the reflection structure.
