Phase change materials (PCMs) are materials that can change their optical properties by switching between different phases in response to external stimuli, such as temperature, light, or electric field. This makes PCMs promising for tunability and reconfigurability of nanophotonic devices, including switches, modulators, and sensors. PCMs can be classified into two categories. The first...
The development of coherent XUV radiation sources is leading to significant advancements in imaging and ultrafast studies. High harmonic generation (HHG) is one technique used to generate laser based coherent ultrashort XUV pulses but is relatively inefficient. This process is normally carried out in the beamwaist of a focused laser and, because of the limited intensity range for efficient...
The terahertz (THz) frequency band, lying between the microwave and infrared regions of the electromagnetic spectrum, has enabled significant developments in a variety of fields such as wireless communications, product quality control, and condensed matter research. To improve the photonics systems used for these applications, intense efforts are being made to develop faster and more sensitive...
With many regions of the electromagnetic spectrum already being allocated for wireless communications in mobile, satellite and military sectors, there is a growing need to exploit new frequency regions. The terahertz (THz) band, which lies between the microwave and infrared regions, serves as a possible solution to achieve high data transfer rates at Terabytes/sec (Tbps). For transmission in...
