HP-1-26-1 / Making microwaves with light at the quantum limit and beyond
* Thomas Schibli, University of Colorado, United States
Precision measurements enabled by exquisitely stable optical sources had a profound impact on the optical metrology enterprise. What is perhaps lesser known is that similar optical tools enable ultra-stable microwave sources and measurement techniques. Here, we will discuss the opportunities and challenges of laser-driven low-noise microwave generation in the presence of quantum and technical noise in laser, detection and characterization systems.

We demonstrate coherent control in a semiconductor using vector laser beams and laser beams tailored with spatial light modulators. We spatially map the resulting current vector distribution using optoelectronic detection.

Tunable, time-locked ultrafast pulse pairs are crucial for time-resolved spectroscopy. We demonstrate tunable (305–570 fs; 1.6–2.9 nm) pulse generation from a continuous beam via optical Kerr switching in a 10 cm single-mode fibre. Our system is also capable of 2- and 4-pulse train generation. Results highlight a simple, low-cost device capable of configurable ultrafast pulse generation, with further application in ultrafast time-gating.

this report experimentally demonstrates the generation of ultra broadband supercontinuum (SC) light source in mid infrared by using self-started mode-locked fiber laser centered at 1550nm. Ultra short pulse of 17ps with high average power generated SC in ZrF4 (ZBLAN fluoride fiber).
