    [ 1 ] Fundamental and Applied Studies for advanced Sub-THz

    (Millimeter-Wave) Imaging Radar   (NSC, Aug. 1, 2012-July 31,


    To date, we have demonstrated W-band (0.1 THz or 100 GHz) Radio-over-fiber communication with data rate beyond 20 Gbit/s. The key technologies are (1) photonics-based W-band MMW source and the sub-THz (MMW) photonic transmitter. In this work, we will further develop the source such that higher-power MMW generation at operation up to the J-band (200-400 GHz) with dynamic adaptive control would be possible. Such sources will be used for the MMW imaging Radar and sensing applications. We will also look into the potential of multiple-input-multiple-output (MIMO) Radar convergence with optical-frequency-division-multiplexed MIMO communication so that an integrated platform for both communication and radar could be established for cost and power consumption reduction. We will also conduct diagnostics on high-speed photodiodes and photonic transmitters developed by our collaborators.

    [ 2 ] Table-top Sub-Single-Cycle Attosecond Laser Sources (II)  (NSC, August 1. 2012 - July 31, 2015)

    Attosecond (1 as = 10-18 sec) science, because its potential for unlocking the ultrafast dynamics in the nano-world, is generally recognized as one of the frontier areas in science today. In our on-going work, we have successfully constructed a sub-femtoseocond (attosecond) coherent light source by starting from a single nanosecond laser and phase lock the cascaded harmonics generated by second-order nonlinear optical processes. This source will be fine-tuned such that a time-resolution of several tens of attosecond can be realized. We proposed to construct an apparatus for the generation of higher-order harmonics (HHG) assisted by surface plasmon polaritons and the characterization of the synthesized pulse train. Taking advantage of the capability of the present source for amplitude and phase control of the individual harmonics, an optimized electric waveform for driving the electrons for highly efficient HHG should be possible, which was proposed theoretically previously. Phase effects should also be evident even for harmonic generation in the perturbative regime (nT£   9). More efficient generation of such lower harmonics should be possible. The synthesis of first nine harmonics should already allowed us to generate transform-limited pulses shorter than 200 as, with wavelength extending to the VUV region, i.e., 118 nm. More precise synthesis of arbitrary light waveforms should also be possible with 9 components as opposed to five in the present source. We also intend to investigate the feasibility of material processing, e.g., ablation, with the present source, based on preliminary results.


    [ 3 ] Research and Development of Advanced Fiber Laser Systems and Their Applications, PI (NSC Industrial co-op with Cleverwave Corp. and POFC, June 1. 2013- May 31, 2016)

    Laser machining and processing of materials are among the most important applications of the laser. Taiwan has a robust laser processing industry. Regretfully, almost all of the high-power lasers used in the processing centers are imported. Lasers of different specifications are needed for versatile applications ranging from precision resistor trimming, scribing for the solid-state lighting and solar cell industry, laser annealing and activiation. Up to now, we have successfully developed 10-ps-class high-average-power (> 50 W at 1慆m) Yb-doped fiber laser systems and green output > 5W. In this follow-up project, we propose to develop high-pulse-energy ns, ps and fs Yb-fiber lasers for the above mentioned applications. Through efficient nonlinear frequency conversion, green laser which wavelength is 532nm and UV laser output at 266 nm will be generated as well. Critical components such as fiber adaptors developed in the project should also be useful in fiber communication and sensing system.
