Title: OPTICAL PATH CONVERSION ELEMENT, CONNECTION STRUCTURE FOR OPTICAL PATH CONVERSION ELEMENT, LIGHT SOURCE DEVICE, AND OPTICAL MOUNTING DEVICE
Abstract:
This optical path conversion element (4) is provided with: a support substrate (5); a thin layer (6) comprising an optical crystal formed on the support substrate, the thin layer having a first principal surface side (6a) situated on the support substrate side, and a second principal surface side (6b) situated on the opposite side from the support substrate; and a ridge optical waveguide (8) partitioned by at least a pair of ridge grooves (7) formed in the thin layer (6), the ridge optical waveguide having a light entrance face (8a) and a reflecting face (8b) for reflecting light propagated through the optical waveguide (8). Light reflected by the reflecting face exits the surface through the thin layer.
