...insulator (LNOI) platform rib-loaded by silicon nitride (SiN) for telecommunications. Major contributions made by this project include the development of a design approach based on coupled mode theory that enables the creation of adiabatic devices with minimal footprint. This approach is verified by creating polarization mode converters on the silicon-on-insulator (SOI) platform. Next, several studies on the deposition, patterning and bonding of SiN thin layers are presented. Finally, an adiabatic polarization beam splitter/rotator (PBSR) is realized on the SiN/LNOI platform. The PBSR consists of two stages: an adiabatic mode converter and an adiabatic coupler. This pushes the boundaries towards high speed and low power communication as well as applications for different w...

Video Streaming Protocol to Payload Only Converter DLL This a requirements type doc for a dll to be written by an outsourced software engineer. Background I have a need to collect data from a video source via Ethernet ,and translate the data into TTL for sending out RF. The receiving side receives the TTL data and converts it back to Ethernet. The problem is most streaming video devices only output the video via some streaming protocol, typically RTSP. I don’t know how to strip off the payload from that streaming protocol, so I have to use a tool. Currently using to do that. The problem with that is the latency from the actual video source to the data that needs to get rendered. It’s about 2 seconds with VLC, which is way too long for my use. Requirements 1. ...
