For future 65 nm and smaller nodes, thermal anneal processes in the ms and mus range are required. Based on laboratory tests using the line scan method, an R&D system has been developed.
Reliability and lifetime of quasi-CW laser diode arrays are greatly influenced by their thermal characteristics. This paper examines the thermal properties of laser diode arrays operating in long pulse duration regime.
It is shown that the rate of two-photon absorption can be greatly reduced by the generation of entangled photon holes that are analogous to the holes of semiconductor theory.
A new type refractive homogenizer provides a 98% light throughput. Special lens form of the microoptic raster elements solves usual problems with interference and diffraction effects even for a small NA.
A membrane photonic crystal cavity coupled to a waveguide is fabricated and characterised. Fabry-Perot method was used to measure propagation losses. We show that coupling results in asymmetric features in the transmission suitable for high-speed analog modulation.
Femtosecond pulses coupled to hollow-pyramid near-field probes allow achieving sufficient peak power to perform near-field nonlinear optics. We present second-harmonic generation images of nanostructured metal surfaces with spatial resolution better than 100 nm.
Localized and propagating surface plasmon dynamics in Ag films are imaged by time-resolved photoemission electron microscopy with <10 fs time and d~40 nm spatial resolution. Movies of plasmon dephasing are recorded with 330 as/frame rate.
We propose a tunable spectral bandpass filter using short- and long-wavelength bend-loss edges of both MSF and HOF. Various spectral functionalities of filter are obtained by carefully choosing optimal bend radii for serially concatenated fibers.
We report on a singly resonant injection seeded optical parametric ring oscillator with signal pulse energy of up to 38 mJ, 50% pump depletion, spectral purity of 99.97%, and M2 of about 6.
Cross-phase-modulation-induced pulse delay or advancement in an optical fiber is analyzed. It is shown that XPM and group-velocity mismatch can lead to controllable pulse delay or advancement with negligible frequency shift.
RIN characteristics in a frequency stabilized MSL were experimentally and theoretically investigated. Average RIN level of less than -150 dB/Hz as well as Modal RIN reduction of approximately 3 dB were obtained from the frequency stabilized MSL.
We show analytically and numerically that a stationary rescaled pulse (SRP) can exist in a dispersion decreasing fiber with a linearly decreasing dispersion profile. By using the SRP, we demonstrate extremely pedestal-free pulse compression.
Full quantum theory of the optical two-qubit quantum phase gate for single photons is formulated. Trade-off between the conditional phase shift and gate fidelity is found, but could be compensated in transient regime.
CdSe QDs in sol-gel films are promising for nonlinear optical waveguide devices. We measured the two-photon absorption (TPA) coefficient at 820 nm in such films, and TPA-induced fluorescence over the 730-980 nm wavelength range.
Pulses from an ultrafast oscillator are conditioned, amplified, and delivered in an all-optical-fiber architecture. Combined with an electro-optic receiver, the complete system delivers a 4-V electrical trigger with less than 400 fs additive jitter.
This paper deals with the microstructure of the generated crystals in borate glass by femtosecond laser irradiation, Raman spectroscopy was used to study the distribution of the two phases of barium metaborate crystals produced.
We report our progress towards the realization of a tunable and narrow-band source of correlated photons for coherent manipulation of cold atoms, using a combination of four-wave mixing and electromagnetically induced transparency.
We experimentally observed the self-distortion of picosecond pulses propagating in silicon wire waveguides. The asymmetry of output pulse shape was due to two-photon absorption generated free carriers within the pulse duration.
A diode pumped Yb:YAG regenerative amplifier has been developed for short pulse generation. Average output power of 10 W was achieved at pulse repetition rate of 100 kHz with 6.2 ps pulse width.
Sub-10-fs visible pulses allow real time detection of coherent phonons in single-walled carbon nanotubes. Nonlinear coupling between radial breathing (250 cm-1) and the carbon-stretching (1600 cm-1) modes is experimentally observed and theoretically modeled.
