摘要： In a two-way optical communication device, a rising mirror bends light transmitted from a light-emitting element in a virtually perpendicular direction to a surface of a substrate, and the light is gathered on an end of an optical fiber via a light-gathering mirror having a curved surface and is coupled to the optical fiber. Further, in the two-way optical communication device, received light, that is propagated from the optical fiber, is reflected on the light-gathering mirror and is gathered on the light-receiving element. The two-way optical communication device can transmit and receive light through a single optical fiber, causing only small loss in transmission and reception, so that light can be efficiently coupled to an optical fiber such as a POF having a large diameter.

摘要： Numerical aperture of transmitted light is varied to NAs by a transmitting lens. The numerical aperture, NAs, of the transmitted light is made larger than the numerical aperture, NAp, of an optical fiber, whereby the numerical aperture, NAf, of received light radiated from the optical fiber is made smaller as the transmission distance increases. A receiving optical system is arranged such that the receiving efficiency of the received light is increased by the provision of an aperture member according as the numerical aperture, NAf, is made smaller. This improves the receiving efficiency when the transmission distance is long and reduces a variation in the received light quantity even if the transmission distance is varied.

摘要： In a submount main body (1) composed of a single crystal silicon, a mounting surface (4) on which a light-emitting device (11) is mounted is composed of a (100)-oriented surface and the inner surface of a through hole (3) which is formed by anisotropic etching is parallel to the (110)-oriented surface. The light-emitting portion of the light-emitting device (11) is arranged to face a device-side opening (31) which opens into the mounting surface (4) of the submount main body (1). Consequently, heat generated in the light-emitting device (11) can be discharged to the outside more efficiently than the case where the light-emitting portion is arranged to face a side opposite to the submount side. Specifically, light from the light-emitting device (11) is reflected by a reflective surface formed on the surface of the through hole (3), and highly efficiently transmitted outside of the submount main body (1).
