摘要：

We have used laser direct fabrication techniques to implement optical delay lines on an epitaxial GaAs/AlGaAs substrate. These integrated photonic circuits, which are important for optically-controlled phased-array radar, include asymmetric splitters with various splitting ratios, smoothly curved 90 degrees bends, as well as linear waveguides. The delay Lines were tested and found to have the desired delay and a power-output uniformity of +/- 2-4%.
