Abstract
A multiwavelength optical device includes a substrate; a first mirror section including a plurality of first mirror layers stacked on the substrate; an active layer stacked on the first mirror section, the active layer including a light emission portion; a second mirror section including a plurality of second mirror layers stacked on the active layer; a first electrode disposed between the active layer and the second mirror section; and a second electrode disposed between the first mirror section and the active layer.
Claims11
An optical device comprising:
- a substrate;
- a first mirror section including a plurality of first mirror layers stacked on the substrate;
- an active layer stacked on the first mirror section, the active layer including a light emission portion;
- a second mirror section including a plurality of second mirror layers stacked on the active layer;
- a first spacer layer provided between the first mirror section and the active layer;
- a second spacer layer provided between the second mirror section and the active layer;
- a first electrode having at least one portion disposed at a lower stack than the second mirror section and contacting with the second spacer layer;
- a second electrode having at least one portion disposed above the first mirror section and contacting with the first spacer layer;
- and
- an insulating groove section configured to penetrate the second mirror section, the second spacer layer and the active layer,
- wherein the first electrode is disposed in a first hole provided inside the insulating groove section, the first hole extending to a boundary between the active layer and the second spacer laver, and
- the second electrode is disposed in a second hole provided outside the insulating groove section, the second hole extending to a boundary between the first spacer layer and the active layer.
