SYNOPSIS
Optics is used in today’s large-scale computer systems and their communication networks, and integrated optics can provide significant benefits in some areas. For example, research on silicon photonic transceivers began in universities and research labs in the 1990’s, and is now led by large companies, such as Intel, IBM, Oracle, etc. to potentially benefit interconnect technology.

Looking ahead, silicon photonics can serve our desire to measure, control, shape or even generate the electromagnetic spectrum, redefining the conventional metrics for optical devices and subsystems - how small, how much power, how fast, etc. – by many orders of magnitude, while adding the benefits of CMOS electronic compatibility, scalability and manufacturability. This change is happening recently, and will work its way to industry in the coming years.

I will present examples of some devices and subsystems we have designed:
i) An reconfigurable network node for a data center network “MORDIA” (a single-chip miniaturization of a rack-mounted shelf of conventional telecom components)
ii) WDM power monitoring on a chip with no scanning / moving parts, which can measure the spectrum in less than the duration of a TCP/IP packet
iii) Wavelength conversion with only a few mW of pump power, and the integration of mixers and high contrast (&#gt;40 dB) filters on the same chip, with tuning knobs
iv) The first heralded single-photon source from silicon, and photon pair generation in multiple spectral lines (comb) and controllable joint-spectral intensity
