Skills

1. Lasers

Ultra-fast laser systems :

• Coherent MIRA900/REGA9000 (180 fs, 4 µJ/pulse, 800 nm 250 kHz),

• Spectra Physics SpitFire (45 fs, 1 mJ/pulse, 800 nm, 1 kHz),

• KML oscillator.

CW lasers :

• Fiber integrated tunable Littman external cavity diode lasers (Sacher Lion TEC520), operating at 0.78 µm, output power ~100 mW,

• He-Ne-lasers,

• Diode lasers operating at 0.78 µm, 0.83 µm, 1.31 µm, 1.55 µm.

2. Materials

• Gold nanoparticles (colloid, and dried samples),

• Electro-optic polymers,

• Electro-optic crystals (ZnTe, ZnCdTe, GaAs),

• RDX explosive,

• Photopolymers.

3. Experiments

• AFM imaging. Random aggregated gold nanostructures on the glass substrate were fabricated and imaged with an AFM. Surface roughness of 30-400 nm has been observed. Enhancement of 4000 times in Raman and CARS spectra has been achieved.

• Terahertz interferometric imaging. Two fiber integrated Littman external cavity diode lasers are mixed in a 2x2 fiber coupler to power both THz emitter and detector (Low-Temperature Grown GaAs bowtie-type photo-conductive dipole antennae). THz radiation is generated at a beating frequency of lasers. Synthetic aperture interferometric images are calculated through Fourier inversion after correlation of THz detectors at several locations.

• Terahertz generation and detection using EO crystals and polymers. A femtosecond laser beam is split into pump (90%) and probe (10%) parts. The pump beam is incident onto the EO polymer or crystal emitter which is located at the focus of an off-axis parabolic mirror. The generated THz beam is collimated and focused into the polymer or crystal sensor by a pair of off-axis parabolic mirrors. THz radiation is generated via optical rectification in the nonlinear emitter and detected using the linear EO effect.

• Terahertz spectroscopy. Terahertz time-domain spectroscopy allows to obtain a spectrum in a single terahertz pulse. CW terahertz radiation at several frequencies also allows to reconstruct a spectrum. An excellent agreement of C-4 spectra obtained by both these methods around a spectral peak at 0.82 THz has been demonstrated.

• Holography. A He-Ne-laser beam is split into reference (50%) and signal (50%) parts which are cast on the surface of a photopolymer layer. Thick volume phase diffraction gratings are recorded without any wet processing through a refractive index modulation via photochemical reaction in the photopolymer layer sensibilized at 610 nm. Another laser operating at 780 nm (out of the photopolymer absorption) is used to probe the phase grating and measure its diffraction efficiency.

4. Lab skills

• Atomic force microscope (Nanonics, MultiView 4000),

• Optical components (lenses, mirrors, filters, polarizer’s, beam splitters, etc.),

• Lab electronics (multimeters, oscilloscopes, lock-in amplifiers, function generators, power supplies, etc.),

• Optical equipment (power meters, infrared viewers, microscopes, refractometers, spectrometers, profilometers, optical spectrum analyzers),

• Clean room (fume-hoods, mask aligner, spin-coating machine).

Results

• As a research assistant of the Subfemtosecond Science Lab at the Texas A&M University I was working with gold nanoparticles. I performed the synthesis of gold nanoparticles in colloid and used them to fabricate random aggregated gold nanostructures on the surface of glass slides. These gold nanostructures were used to observe enhancement of Raman and CARS spectra.

• As a postdoctoral research associate of the THz spectroscopy and imaging group at the New Jersey Institute of Technology I obtained experimental results:

1. One-dimensional and two-dimensional interferometric images of a C-4 sample have been obtained at several THz frequencies to demonstrate the potential of this method for a stand-off detection of explosives.

2. Phase modulation technique has been implemented to reduce the imaging time from 2 hours to ~3 min.

3. Focusing issues of interferometric imaging have been studied.

4. In collaboration with Alcatel-Lucent Technologies, a record 1.5Mb/s data THz transmission at the distance of ~1m with a bit error rate of 10-9.

5. Interferometric images of two point sources have been simulated; an excellent agreement of simulated and real images of a point source has been observed.

• During my graduate study at the University of Maryland, Baltimore County, I was a research assistant in the Nonlinear Optics group:

1. I developed a fabrication technique for thick poled EO polymer layers. These methods have been successfully used for several polymer composites.

2. These poled EO polymers were used for efficient THz generation and detection with bandwidth >10 THz. The US patent "Broadband gap-free 12 THz spectrometer based on electro-optic polymers" has been filed.

3. A resonance enhanced THz generation near the absorption maximum has been observed resulting the THz field generated from a 3 µm thick CFAPC layer to be greater than that of 1 mm ZnTe reference.
