摘要：

Waveguide-type directional couplers with different waveguide widths in the coupling region are fabricated based on high silica on Si technologies. These asymmetric couplers show wavelength-flattened coupling ratios of 50% ± 5% over the l·2μm-l·6μm wavelength range. © 1990, The Institution of Electrical Engineers. All rights reserved.
