Metasurface Optical Pulse Shaper for Shaping an Optical Pulse in a Temporal Domain

NIST Inventors
Henri Lezec, Amit Agrawal, Wenqi Zhu, and
Patent Description Ultrafast laser pulse shaping is a well-developed field with available commercial products. Typically, the amplitude, phase or polarization of the light is controlled by placing a spatial light modulator (SLM) at the focus of the first mirror, in a technique known as Fourier
The figure shows a microfabricated optical probe with the following components: 110 - optical loop, 111 – structured region of 110, 114 – optical waveguide, 116 – first arm of optical  waveguide, 120 – substrate, 122 – optical cladding layer, 124 – first single mode optical fiber, 126 – primary light, and 128 – output light.

Microfabricated Optical Probe

NIST Inventors
Vladimir Aksyuk and Kartik Srinivasan
Patent Description Integrated photonics research and manufacturing requires a probe for in-line nondestructive optical testing of devices. Current optical probes require dedicated and large coupling areas in the photonic circuit. They cannot provide sufficient control over the degree, location and
