Compact mid-infrared transmitter and receiver for free-space satellite communications

Saeed Salimian Rizi, Liam Flannigan, Ross Cheriton, Daniel Poitras et autres

We demonstrate a compact mid-infrared (MIR) free-space optical transceiver based on packaged, fiber-coupled intracavity difference-frequency generation (DFG) and sum-frequency generation (SFG) modules operating at room temperature. The system achieves stable MIR generation, recovery of modulated signals up to 1.3 Gb/s, and outdoor …

The Aerosol Limb Imager: multi-spectral polarimetric observations of stratospheric aerosol

Daniel Letros, Liam Graham, Adam Bourassa, D. A. Degenstein et autres

The Aerosol Limb Imager (ALI) is designed to measure stratospheric aerosol by imaging limb-scattered sunlight. Each image taken by ALI is spectrally filtered at a tunable wavelength and refined to consist of either horizontally or vertically polarized light. Novel to limb imaging, …

Weak Emergence: One from Many

Liam Graham

High level properties such as temperature, hardness or roundness are multiply realized: they are shared by systems with different microphysical makeups. Such properties are multiple realization (MR) emergent in the sense that they provide useful explanations independent of the details of their …

More Seems Different

Liam Graham

This chapter introduces the concept of emergence using a broad range of examples. These start from inside the atomic nucleus and work up through chemistry and biology to evolution and mind. While exploring these examples, many concepts that will play an important …
