Details of the Technology Offer
Generic Architecture for Converting Electrical Data to Optical Pulses
Optoelectronics / Photonics, Optoelectronic Computing & Optical Communication
- There is a growing demand to process larger volumes of digital data at ever increasing speeds plus exponential growth in performance of the basic microelectronic components
- Current interconnection network, comprising multilayered complex of parallel electrical conduits, is a major bottle neck
- Optical communication links provide effective, fast transport for large volumes of digital data over long distances in telecommunication
- Problem: electronic data is in the form of digital, parallel-electronic words while optical data is organized as a serial string of photonic bits or digital, serial-optic words – need method for cost-effective conversion.
Fast electronic/optical interconnectivity for processing digital data
ORTA is a generic architecture for converting between digital, parallel-electronic words and digital, serial-optic words incorporating two processes:
- Conversion between parallel and serial signals by complex multiplexing or de-multiplexing; and
- Conversion between the electronic and the optic representations of the signals using fast electronic devices and optoelectronic modulators.
- Generic architecture optimized for conversion of digital data back and forth from electrical pulses to photonic pulses
- Effective for data conversion from electronic circuit to optical fiber and vice versa
- ORTA operates at the rate of the data processing of the electronic processors without the need for ultrafast optoelectronic transmitters and receivers
- Preliminary design of a specific embodiment of the ORTA concept using simulation tools.
