A disclosed semiconductor laser module includes a semiconductor laser device; a waveguide optical function device that has an incidence end on which laser light emitted from the semiconductor laser device is incident and that guides the incident light; and a protrusion that is provided on an extension line of a light path of the laser light emitted from the semiconductor laser device, the extension line extending beyond the incidence end.

Semiconductor laser module and method of manufacturing semiconductor laser module

A flexible substrate has an insulating base member and a conductive layer that is formed on the base member and includes an electrical connecting portion fixed to a component and electrically connected to the component, and the flexible substrate includes: a main portion on which the electrical connecting portion is formed; and a protruding portion provided so as to protrude from a portion of the main portion in which the electrical connecting portion is formed, wherein the main portion is bent along a first bending line extending in a first direction, and wherein the protruding portion can be bent along a second bending line extending in a second direction intersecting the first direction and is adapted to reduce stress occurring at the electrical connecting portion by the protruding portion being bent along the second bending line.

Flexible substrate, flexible substrate-attached component, and manufacturing method of flexible substrate-attached component

An optical module includes an optical element configured to be driven at a high frequency, a circuit board arranged at a height different from a height of the optical element, and a wiring sub-mount including a wiring electrically connecting the optical element and the circuit board, the wiring being such that a height of a connection surface of one end portion of the wiring and a height of a connection surface of another end portion of the wiring are different from each other.

Optical module

An optical element module includes a casing having a bottom plate, a temperature-adjusting unit being mounted on the bottom plate in the casing and having at least a lower layer portion and an upper layer portion positioned above the lower layer portion, a support member mounted on the temperature-adjusting unit in the casing, and a semiconductor laser element being mounted on the support member and outputting a laser light to a forward side. The upper layer portion of the temperature-adjusting unit projects at a backward side of the semiconductor laser element relative to the lower layer portion.
