研究興趣與成果   (Updated on March 24, 2021)

[ 1 ] Multi-color Light-Matter Interaction II (MOST, Aug. 1, 2020 - July 31, 2021)
This project is a continuation of our 2019-2020 project. In short, we propose to study light-matter interaction with two types of novel laser sources, i.e., phase-controlled multi-color femtosecond synthesized waveforms and noise-like laser pulses. There are two focuses of the present study: Material Processing and THz Science and Technology. Types of material processing to be investigated include activation of source/drain dopants for silicon technology beyond CMOS, recrystallization of amorphous thin film for display and solar cell applications, fabrication of hyperdoped silicon and transparent electrodes for photovoltaic, imaging and IR optoelectronic applications. The mechanisms for processing by these novel sources is expected to be different from conventional approaches and would allow us to shed more light on the fundamental problem of laser-material interaction. In particular, the effect of relative phases among coherently controlled multi-color beams on light Vmatter interaction has not been explored extensively. The other focus of the present project is multi-color excitation of broadband THz radiation in air plasma and dielectric media. Our preliminary theoretical studies show that enhancement in efficiency by several orders of magnitude would be possible with optimum relative phases of the three-color excitation pulse over the two-color case. On the other hand, noise-like pulses may enable generation of THz white light continuum.? Such THz sources would be attractive sources for diagnostics and analysis of advanced material prepared in this project and elsewhere.

[ 2 ] Novel non-absorbing facet in high power laser diodes II (Science Park R&D Endeavor Project with Turning Point Lasers Corporation, May 1, 2020 - April 30, 2021)

High-power laser diodes (LDs) ?are key components for the high-tech industry and advanced manufacturing. For example, LDs with center wavelengths of 915 nm or 976 nm are used to pump Yb-doped fiber lasers, which are now widely employed for material modification and machining. The conversion efficiency of the Yb-fiber lasers pumped at 976 nm is much higher than those pumped at 915 nm. However, the requirement on wavelength accuracy and stability is quite stringent at 976 nm.? If the output power of LDs can be scaled up, these can be directly used for various applications. In this project, we will employ Quantum-well-intermixing (QWI) technology to develop non-absorbing mirror (NAM) for high-power laser diodes (LDs, l= 76nm). Such LDs will be integrated into a module containing Volume Bragg Grating (VBG) for wavelength stabilization.? Still higher power will be generated by exploring WBC (Wavelength Beam Combine) technology. WBC is also expected to enhance the beam quality of high-power LDs thus constructed.

?[ 5 ] Carrier Dynamics and Electrical Properties of LargE Bandgap Semiconductors investigated by Terahertz Spectroscopy (CELESTA, MoST-ANR Bilateral Research Project, year 4, Jan. 1, 2020 - Dec. 31, 2021)

In this Taiwan-France project, we aim at addressing carrier dynamics in large bandgap materials, like ITO (3.7~3.9 eV), TiO2 (3.2 eV), GaN (3.4 eV), etc. ITO and GaN are important for high-speed electronics or optoelectronics while TiO2 is important for application such as water catalysis for removing pollutants. In both cases, material nano-structuration (nanorods or nanowhiskers) is expected to yield exotic features. For example, the Taiwanese group shows that ITO nanostructures exhibit a significant increase in transmittance (from 9% to 70% up to 15 THz) compared to the bulk film while InN nanorods can enhance photo-excited THz emission. In the proposed joint work, new designs will be tested during this project to provide optimized ITO material and nanostructures. These samples will then be fully characterized. Their electrical conductivity will be investigated by THz-TDS. The dynamics of the carrier population will be studied by UV pump-THz probe time-resolved spectroscopy. For comparison, TiO2 nanofilms and GaN nanostructures will also be studied.

The Taiwanese groups will leverage their expertise in THz technologies, metamaterials, nanodevices and solar cells to design, fabricate and characterize the samples, e.g., using a very broadband THz-TDS system based on THz generation and detection in air. Complementary THz conductivity characterization (polarization, scattering K) will be performed in France, at the IMEP-LAHC Institute (Universite Savoie Mont-Blanc), in particular UV-THz pump-and-probe measurements. Ultimately, the French group will study electron injection in water from optically excited TiO2 in order to achieve a more comprehensive understanding of processes involved in water catalysis in solar-excited depollution systems.

The project can have a real impact on display and optoelectronics devices as well as high-speed electronics since large bandgap semiconductors are a key material in these applications. Moreover, the knowledge acquired during the project in the domain of UV-induced carrier injection of water makes it also relevant to applications in environmental improvement and water purification.
