摘要	A method and apparatus are disclosed whereby integrated optical circuits having waveguide ends of lens geometry are formed which improve the waveguide's optical coupling to light sources and detectors. A channel waveguide is formed on a substrate and the waveguide ends are shaped into lens form by etching to form a protrusion and heating the waveguide to or above the softening temperature of core material of the waveguide resulting in surface tension in the core material that functions to shape the protrusion into a substantially cone-shaped lens end having a smooth surface.
其他摘要	公开了一种方法和装置，由此形成具有透镜几何形状的波导端的集成光学电路，其改善了波导与光源和检测器的光学耦合。在基板上形成通道波导，并且通过蚀刻将波导端部成形为透镜形状以形成突起并将波导加热到或高于波导的芯材料的软化温度，从而在芯材料中起到表面张力的作用。将突起成形为具有光滑表面的基本上锥形的透镜端部。
