Abstract: Systems and methods disclosed herein use a multi-color pyrometer configured to determine a first temperature in a high temperature range and a single-color pyrometer configured to determine second temperature in a low temperature range. The system uses information gained from determination of the first temperature in the high temperature range to facilitate later determining the second temperature in the low temperature range. The first temperature in the high temperature range and the second temperature in the low temperature range are used to monitor and control different engine operations that occur at different times.

Abstract: A photonic circuit integrated on a silicon-on-insulator waveguide, the silicon-on-insulator waveguide including a guiding layer, a cladding layer, and a substrate layer. The guiding layer having a first surface and a second surface, the second surface abutting one surface of the cladding layer, the cladding layer having another surface in abutment with a surface of the substrate layer, a photon pump in optical communication with the guiding layer, a nonlinear optical material in contact with the guiding layer first surface, a photon beam of the photon pump traversing the silicon-on-insulator waveguide, and the silicon-on-insulator waveguide having an output beam that includes a signal beam and an idler beam.
