“…Another approach to cope with disorder-related issues and restore the proper behavior of CROWs would be to perform a post-fabrication trimming procedure of the structure parameters after testing the device with specific monitoring techniques to retrieve the phase errors [155,156]. To this end, photosensitive materials such as polymers and chalcogenide glasses have been successfully employed [101,102].…”

A century after the first optical cavity, coupled resonator optical waveguides (CROWs) were conceived as a new way to guide light on a photonic chip. Controlling chains of coupled resonators to let light propagate through, with a reduced speed and enhanced intensity, boosting light-matter interaction while keeping information undistorted: this was the fascinating promise of CROWs, but also one of the most ambitious challenges ever set for integrated optics. The first decade of the history of CROWs is discussed in this review, from the original idea to recent applications, panning through the technological platforms that have been employed to realize these structures. Design criteria and management issues, fundamental limits, and sensitivity to fabrication tolerances are discussed to make the reader aware of the performance of state-of-the-art CROWs and to provide a realistic perspective of future applicative horizons.

“…Whereas other configurations might isolate the collected signal using a pinhole and photodiode, 37 our scheme relies on the position sensitive detection capability of the photodetector camera, similar to what has been reported for measurements on multiple ring resonator systems. 38 The vertical radiation spectra similarly reveals the single high Q-factor resonance at 1513.9 nm, but with an even higher signal-to-noise ratio, confirming that both the measured Q-factor and $0.12 transmission level are limited by the radiation losses. Lorentzian fitting of both resonance measurements reveals a measured quality factor, Q meas $ 7.42 Â 10 3 .…”

We present and experimentally demonstrate a slotted photonic crystal single nanobeam cavity in silicon. The slot geometry is exploited to achieve ultra-small effective mode volumes, ~0.025({\lambda}/n)^3, more than an order of magnitude smaller than traditional nanobeam cavities. A continuous slot and a tapered photonic crystal design are implemented to achieve experimental quality factors near 10^4. This device structure offers a unique platform for achieving enhanced light-matter interactions and could be used to benefit a variety of applications including non-linear optics, cavity quantum electro-dynamics, sensing, optical modulation, and nano-optomechanics.Comment: Accepted to Applied Physics Letter

Adiabatic elimination-based coupling control in densely packed subwavelength waveguides

et al. 2015

View full text Add to dashboard Cite

The ability to control light propagation in photonic integrated circuits is at the foundation of modern light-based communication. However, the inherent crosstalk in densely packed waveguides and the lack of robust control of the coupling are a major roadblock toward ultra-high density photonic integrated circuits. As a result, the diffraction limit is often considered as the lower bound for ultra-dense silicon photonics circuits. Here we experimentally demonstrate an active control of the coupling between two closely packed waveguides via the interaction with a decoupled waveguide. This control scheme is analogous to the adiabatic elimination, a well-known procedure in atomic physics. This approach offers an attractive solution for ultra-dense integrated nanophotonics for light-based communications and integrated quantum computing.
