Early life and education

Poon was born in Hong Kong and grew up in Toronto. [3] She obtained a B.A.Sc. in engineering from the University of Toronto in 2002 and an M.S. in Electrical engineering from California Institute of Technology in 2007. [4] She stayed at Caltech to carry out her PhD under the supervision of Professor Amnon Yariv. [5] Her thesis studied ways to control slow light in optical waveguides and was awarded the Milton and Francis Clauser Doctoral Prize. [6] During her graduate studies, she founded Caltech's Student Chapter of Optica. [3]

Research and career

In 2007, Poon moved back to the University of Toronto, where she is now Professor of Electrical and Computer Engineering. Her early research continued investigating waveguide resonators. [7] [8] While at Toronto, she built a research team focused on studying silicon-based integrated photonic technologies for applications in telecommunications. [9] [10] Her research group also focuses on neurotechnology, and investigate how integrated photonic devices can be used to develop new brain imaging techniques. [11] [12]

Poon became an honorary professor at the Faculty of Electrical Engineering and Computer Science at Technische Universität Berlin in 2018. [13] She is also principal investigator at the Neurotech Alliance and the Center for Advancing Neurotechnological Innovation to Application (CRANIA) at the University of Toronto. [14]

Awards and honours

Poon was elected as a Fellow of Optica in 2018 "for outstanding contributions to the research and development of silicon-based integrated optics, including microresonators, electro-optic modulators and integrated hybrid photonics". [15] She is a Director-At-Large at Optica. [2]

She was awarded the University of Toronto's McCharles' Prize for Early Career Distinction in 2013, and named one of the world's Top 35 IT innovators under 35 by the MIT Technology Review in 2012. [16] [17] [18] Poon is a two-time recipient of the IBM Faculty Award (2010, 2011), and also received the Ontario Ministry of Research and Innovation Award (2009) and a University Faculty Award from the Natural Sciences and Engineering Research Council (2008).

<span class="mw-page-title-main">Optical ring resonators</span> Set of waveguides including a closed loop

An optical ring resonator is a set of waveguides in which at least one is a closed loop coupled to some sort of light input and output. The concepts behind optical ring resonators are the same as those behind whispering galleries except that they use light and obey the properties behind constructive interference and total internal reflection. When light of the resonant wavelength is passed through the loop from the input waveguide, the light builds up in intensity over multiple round-trips owing to constructive interference and is output to the output bus waveguide which serves as a detector waveguide. Because only a select few wavelengths will be at resonance within the loop, the optical ring resonator functions as a filter. Additionally, as implied earlier, two or more ring waveguides can be coupled to each other to form an add/drop optical filter.

<span class="mw-page-title-main">Optical circulator</span> Optical device in which light entering any port exits from the next

An optical circulator is a three- or four-port optical device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but instead exits from port 3. This is analogous to the operation of an electronic circulator. Fiber-optic circulators are used to separate optical signals that travel in opposite directions in an optical fiber, for example to achieve bi-directional transmission over a single fiber. Because of their high isolation of the input and reflected optical powers and their low insertion loss, optical circulators are widely used in advanced communication systems and fiber-optic sensor applications.

A photonic integrated circuit (PIC) or integrated optical circuit is a microchip containing two or more photonic components that form a functioning circuit. This technology detects, generates, transports, and processes light. Photonic integrated circuits use photons as opposed to electrons that are used by electronic integrated circuits. The major difference between the two is that a photonic integrated circuit provides functions for information signals imposed on optical wavelengths typically in the visible spectrum or near-infrared (850–1650 nm).

A hybrid silicon laser is a semiconductor laser fabricated from both silicon and group III-V semiconductor materials. The hybrid silicon laser was developed to address the lack of a silicon laser to enable fabrication of low-cost, mass-producible silicon optical devices. The hybrid approach takes advantage of the light-emitting properties of III-V semiconductor materials combined with the process maturity of silicon to fabricate electrically driven lasers on a silicon wafer that can be integrated with other silicon photonic devices.

<span class="mw-page-title-main">Silicon photonics</span> Photonic systems which use silicon as an optical medium

Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication systems. The silicon typically lies on top of a layer of silica in what is known as silicon on insulator (SOI).
