We propose a new type of bistable device for silicon photonics, using the self-electro-optic effect within an optical cavity. Since the bistability does not depend on the intrinsic optical nonlinearity of the material, but is instead engineered by means of optoelectronic feedback, it appears at low optical powers. This bistable device satisfies all the basic criteria required in an optical swit...

This paper introduces a new set-up for the determination of colour change on cultural heritage objects, referred to herein as stereo-microfading tester. The system uses high quality optics through implementation stereo-microscope its central element. technology enables developments such incorporation imaging systems, and separation fading measurement processes. describes this micro-fading evalu...

This paper proposed a fully passive device prototype, named Passive In-line Monitoring (PIM) device, which used to tap out a small ratio of triple-play signals for monitoring purpose without affecting the transmission in tree-structured fiber-to-the-home (FTTH) access network. This device will be installed with the main lines in FTTH permanently to allow the field engineers or technicians to si...
