摘要

在非线性光学应用中，晶圆键合是实现变畴波导的一种有效方法。研究了准相位匹配差频产生(DFG)在晶片键合AlGaAs波导中的波长转换。宽转换带宽(/spl sim/90 nm)、极化多样化操作和极化无关转换效率表明其在WDM网络中的应用潜力。频谱反演和线性转换特性也意味着它能够适应所有的信号格式和协议，包括模拟和调频。通过改进OMCVD生长和制造工艺，可以减少散射损失，从而显著提高转换效率。

Nonlinear optical devices for WDM system applications realized by wafer-bonding

Wafer-bonding is an effective method of realizing a domain altered waveguide for nonlinear optical applications. Wavelength conversion by quasi-phase-matched difference frequency generation (DFG) in a wafer-bonded AlGaAs waveguide has been demonstrated. The wide conversion bandwidth (/spl sim/90 nm), polarization diversified operation, and polarization independent conversion efficiency indicate its potential for WDM network applications. Spectral inversion and linear conversion properties also imply its capability to accommodate all signal formats and protocols including analog and frequency modulation. A significant improvement in the conversion efficiency is expected from reduction of scattering losses by improved OMCVD growth and fabrication processes.
