Ultrafast laser inscription (ULI) is a highly versatile technique for creating index modifications in glasses and crystalline materials. The process of ULI relies on ultrashort laser pulses focused inside of a material. The high intensity of the pulsed beam induces nonlinear absorption processes, which transfers the pulse energy to the material lattice. With careful experimental control of the laser parameters, a permanent change in the refractive can be obtained in the bulk material. The permanent refractive index change obtained by ULI can be used to create waveguides and devices in active and passive materials. In this work, we present recent advances on creation of guided wave devices in Mid-IR compatable materials such as Fe:ZnSe, Cr:ZnSe, Ho:YAG, LiNbO3, and CdSiP2.

Epsilon-near-zero materials such as the transparent conducting oxides have arisen as promising nonlinear materials due to enhanced light matter interactions. However, loss plays a key role. Here we discuss these advances and develop phenomenological models to guide efforts, focusing on the role of loss.

We report the generation of coherent THz frequency combs in high-Q nonlinear microcavities. Driven by a continuous-wave laser and with Lugiato-Lefever formalism, the efficient THz Turing pattern has exceptional robustness and is observed in two-accompanying differential resonators. Square-spectrum combs are also observed, towards THz radiation.

Two-dimensional van der Waals (vdW) materials have emerged as a very attractive class of optoelectronic material due to the unprecedented strength in its interaction with light. Approaches to enhance this interaction even further using photonic structures such as microcavities and metamaterials is highly attractive for both fundamental investigations as well as for applications such as light emitting diodes and quantum technologies.

Conventionally, radar systems use bulky mixer stages at different levels for frequency conversions. In this work, we discuss Up/Down conversion methods based on Optical heterodyne principle that reduces the complexity of modern radar systems. The work is supported with typical modeling and experimental analysis results.
