Problems solved by technology

Therefore, when the structure described in Patent Document 1 is applied to a lens array, there is a problem that it is difficult to form a reflection surface for reflecting monitor light around the lens.
[0013] In addition, in Patent Document 2, since the positional accuracy of the boundary between the total reflection mirror and the notch is required, there is a problem that manufacturing is difficult.

Abstract

Provided is a lens array that can reliably obtain monitor light and is easy to manufacture. In the provided lens array, light incident on a first lens surface (11) from light-emitting elements is split by a reflective / transmissive layer (17) between a first optical surface (14a) and a first prism surface (16a) and sent, respectively, towards a second lens surface (12) and a third lens surface (13). Monitor light included in the light sent towards the third lens surface (13) is sent by the third lens surface (13) towards a light-receiving element (8). The path of light incident on the first optical surface (14a) is collinear with the path of light outgoing from the second optical surface (14b).

Description

technical field [0001] The present invention relates to a lens array and an optical module provided with the lens array, and particularly relates to a lens array suitable for optically coupling a plurality of light emitting elements with an end face of a light transmission body and an optical module provided with the lens array. Background technique [0002] In recent years, so-called optical interconnection (optical interconnection) has been widely used as a technology for high-speed signal transmission within a system device, between devices, or between optical modules. Here, the term "optical interconnection" refers to a technique in which optical components are treated as electronic components and mounted on motherboards or circuit boards used in computers, vehicles, optical transceiver modules, and the like. [0003] Optical modules for such optical interconnects, e.g., in-device or in-device with media converters or interconnections of switching hubs, optical transceiv...
