| 摘要 |
An integrated chip for data communication, telecommunication and optical analysis for at least one, two or more wavelengths where the chip can be used not only to emit light but also to detect light. The invention is characterised in that the chip (1) includes a waveguide (2) with a first port (3), in that the waveguide (2) expands from the first port (3) in the direction of at least one second waveguide (4) and one third waveguide (6) with at least one second port (5) and one third port (7), respectively, these being placed parallel to each other or at an angle to each other, and separated by a certain distance, and in that the various components of the chip (1) are monolithically integrated.
