Research
The future technological advancement will be driven by quantum photonics:
.......the science and engineering of quantum properties of light and matter at micro and nano-scales.
Our research explores the fundamental properties of light in exotic environments to bring innovation in optical engineering.
We may better understand Nature, life, health, mind, spirituality from profound understanding of quantum physics.
*Quantum & Laser Science is the marvel of futuristic technologies*
*Theory is easy when all mathematical steps are clear and pedagogical.*
*Doing Physics without Mathematics is Lame*
*Idea is not cheap, esp those practical ones, not because you have no idea & have to buy it*
Novel photonic structures for engineering applications - artificially engineered structures can control the properties of electromagnetic waves, providing an ultimate control of light for information processing and imaging.
Generation of intense nonclassical light - nonclassical light can be used for quantum communication and quantum computing, but at high intensity, there are more remarkable applications.
Plasmonic optoelectronics - surface plasmon-polariton is a long-known electron-photon excitation. Recently, the race is on to use this effect for subwavelength imaging and potential revolution in optoelectronic devices.
Left-hand materials - artificially structured materials with negative index can bend the propagation of light, serve as perfect lens and cloaking device.
Laser ablation dynamics in materials such as cornea - photorefractive keratectomy, the technology of using laser pulses to shape human cornea, is based on semi-quantitative understanding of laser ablation dynamics. Our research will transform it to a more exact science.
Optical devices based on quantum effects - quantum effects gave use the present microelectronics. the effects can also produce optical transistor and devices that are hypersensitive to motion.
Nonlinear spectroscopy, imaging or microscopy - Nonlinear optical tecnique can be used to detect any chemical constituents remotely, within seconds. Useful for rapid chemical analysis, imaging of biological tissues, counter-terrorism, surveillance and national security.
Ultrashort, ultrafast, ultraintense light source - advanced laser techniques have produced attosecond laser pulses that can be used to probe molecular dynamics. At extreme intensity, the laser can produce filamentation and plasma in the air. One application is for detection/control of lightning.
