Hello all. I did my Ph.D. in experimental quantum optics and quantum information at the University of Toronto under the supervision of Dr. Aephraim Steinberg. I did a post-doc in Ian Walmsley's group at the University of Oxford in quantum optics and quantum information in integrated optical circuits. Following that, I worked in standards and metrology at the National Research Council Canada. I am now an Associate Professor in Physics at the University of Ottawa.

Articles I initiated

• degree of coherence
• interferometric visibility
• acousto-optic modulator
• interferometric visibility
• Wigner quasi-probability distribution
• POVM
• Interaction-free measurement
• Massasauga Provincial Park
• List of types of interferometers

Articles I substantially changed

• spontaneous parametric down-conversion
• coherent state
• Brewster's angle
• coherence (physics)
• principle of minimum energy
• Optical activity

Articles I am changing here and there

• nonlinear optics
• Dispersion (optics)

Articles I want to edit

• Electric Field
• SPIDER
• Quantum optics # History of quantum optics
• Quantum chaos
• Integrated optical circuit

How to add hidden editor notes in an article

Have you ever needed to post an important message to all editors about an article, on the article itself, but thought it would stick out like a sore thumb and ruin the article if you did? Are you reverting many edits on an article because editors just aren't seeing the important message or special instructions on the talk page?

The solution is that you can insert hidden text in the article! That way, only the people editing the page will see your message! Here is how to insert a hidden comment:

1. First, begin the comment by typing <!--
2. Once you have done that, type what you need the editors to read
3. Then, end the comment by typing -->

Once you have completed those 3 easy steps, you won't be reverting as many mistakes!

For example, the following hidden comment has been used in the Meaning of life article, in the Popular views section:

<!--Please do not add 42 in this section. It is covered under the section titled "Popular culture treatments". Thank you.-->

Some more examples of pages that have hidden messages include:

• Main page
• Community bulletin board
• English Mastiff
