Title: Optical waveguide element
Inventor: OKAMOTO KAZUYA
IPC: G02B6/122
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To provide an optical waveguide element which is small and lightweight and which is provided with an autofocus sensor function. SOLUTION: A light source 1, optical waveguides 2, 4, 5, 6 and photodetectors 7, 8 are integrated on a substrate 21. The optical waveguides 2, 5 propagate light radiated from the light source 1 so as to irradiate an object 9. The optical waveguide 6 propagates reflected light from the object 9. The photodetector 7 detects a quantity of light radiated by the light source 1. The photodetector 8 detects a quantity of light propagated by the optical waveguide 6. A quantity- of-light difference detector 13 finds the difference between the detection result of the first photodetector and the detection result of the second photodetector. Whether the difference between the detection result of the quantity-of-light difference detector and a predetermined value is 0 or not is detected by a zero- crossing point detector 101.  Thereby, an optical waveguide element which is provided with an autofocus sensor function can be constituted.
