Title:
光導波路における低損失コンパクト反射方向転換
Document Type and Number:
Japanese Patent JP2008501156
Kind Code:
A
Abstract:
This invention pertains to a device and method for making same. The device includes a substrate suitable for supporting pathways for optical signals; separate pathways disposed on the substrate suitable for propagating optical signals, the pathways including an input and an output optical pathway; and a reflective surface in operative contact with the input and output pathways for receiving an optical signal from the input pathway and reflecting the optical signal into the output pathway. The method for making the device includes the steps of providing two separate optical pathways on a single substrate, one being an input pathway and the other being an output pathway; providing a reflective surface in operative contact with the pathways whereby an input optical signal is passed through the input pathway, reflected by the reflective surface into the output pathway, and passed out of the output pathway, whereby the device can be made on a lithium niobate substrate with titanium-diffused pathways with a loss of about 1.0 dB or less, in a space that is at least 1/5 the space required by the same or similar prior art device.
