摘要 |
A light source circuit transmits light incident from a semiconductor laser source to a plurality of optical devices. At least one optical branch section is formed to branch one input-side optical waveguide at least into a first output-side optical waveguide terminal and a second output-side optical waveguide terminal. A light path length (L1) between the optical branch section and a next-stage optical branch section or the optical device is connected to the first output-side optical waveguide extending from the optical branch section and a light path length (L2) between the optical branch section and the next-stage optical branch section selected such that the absolute value of a difference between (L1) and (L2) is (¼+i/2) times (i is zero or a positive integer) the wavelength of the light transmitted through the light source circuit. |
