Optical Connector Holder for Compact Fiber Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in positioning and orienting optical fibers for coupling with semiconductor devices complicates the fabrication process, and existing solutions fail to achieve a compact optical processing apparatus with stable optical coupling.
Innovation Solution
An optical processing apparatus is designed with a circuit board, a semiconductor device, and an optical connector where the optical connector's holder parts align and support optical fibers in a way that allows them to be optically coupled with the semiconductor device without interfering with the coupling, using a supporting base thinner than the semiconductor device to stabilize the connection and reduce the overall height.

Engineering Contradiction Analysis
1Reliability
If optical fibers are positioned and oriented for coupling with semiconductor devices, then optical coupling is achieved, but the fabrication process becomes complicated
Solution Approach 1:
The holder is designed with pre-formed grooves that guide and position the optical fibers before coupling with the semiconductor device. This preliminary positioning structure eliminates the need for complex post-assembly alignment procedures, thereby achieving stable optical coupling while simplifying the fabrication process
Solution Approach 2:
The holder acts as an intermediary component between the optical fibers and the semiconductor device. It provides a standardized interface with grooves that automatically align the fibers, mediating the coupling process and reducing both fabrication complexity and improving coupling reliability
2Volume of moving object
If the optical connector and semiconductor device are stacked vertically, then compact integration is achieved, but the height becomes the sum of both thicknesses
Solution Approach 1:
The holder extends in the horizontal direction rather than requiring vertical stacking. By utilizing the lateral dimension for fiber positioning and coupling, the design achieves compact integration without increasing the overall height, as the holder's thickness is smaller than the semiconductor device thickness
3Length of stationary object
If the holder thickness is reduced to achieve compactness, then overall dimension is reduced, but structural stability may be compromised
Solution Approach 1:
The holder is constructed from resin material that provides sufficient structural strength despite its reduced thickness. The material composition and structural design (with grooves and holder parts) work together to maintain stability while enabling compact dimensions

AI summary
An optical processing apparatus includes: a circuit hoard having first and second areas arranged in a direction of a first axis; a semiconductor device having an optical coupling element; an optical connector having an optical fiber and a holder with first and second holder parts, and the optical connector being supported by the second area and the semiconductor device disposed on the first area; and a supporting base having a thickness smaller than that of the semiconductor device. The supporting base is disposed between the second holder part and the second area. The optical fiber has a first optical fiber portion supported by the first holder part, and a second optical fiber portion held by the first and second holder parts. The first optical fiber portion has a tip end and a cladding face which is positioned with respect to the optical coupling element and is separated apart from the semiconductor device.
