NONLINEAR OPTICAL INTERFEROMETERS.
, 1982 This dissertation is an experimental study of a novel type of interferometry based on the generation of Second Harmonic (SH) light. In this work interferometers are described in which an interference pattern arises when two SH waves are superimposed ...

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems
Laser &Photonics Reviews, EarlyView.Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Tunable, High Pulse Energy and Narrow Linewidth Gas‐Filled Fiber Laser Across Near‐ and Mid‐Infrared
Laser &Photonics Reviews, EarlyView.A cascaded gas‐filled anti‐resonant hollow‐core fiber architecture enables broadly tunable infrared Raman lasers spanning ∼1.4–4.6 µm while maintaining microjoule‐level pulse energies and gigahertz‐level linewidths. The approach combines a wavelength‐tunable pump laser with optimized Raman frequency conversion, providing a compact route to high ...

Multifunctionality in Silicon Photonics Through Temperature‐Driven Inverse Design
Laser &Photonics Reviews, EarlyView.Temperature‐conditioned inverse design embeds thermo‐optic reconfigurability directly into compact silicon photonic devices. By co‐optimizing a single geometry at 300 K (T1) and 520 K (T2), the same structure supports distinct optical functions, enabling experimentally verified switching and mode conversion without resonant architectures or additional ...
