We demonstrate a novel scheme for photonic generation of chirped millimeter-wave (MMW) pulse with ultrahigh time-bandwidth product (TBP). By using a fast wavelength-sweeping laser with a narrow instantaneous linewidth, wideband/high-power photonic transmitter-mixers, and heterodyne-beating technique, continuously tunable chirped MMW waveforms at the W-band are generated and detected through wireless transmission. Compared with the reported optical grating-based wavelength-to-time mapping techniques for chirped pulse generation, our approach eliminates the problem in limited frequency resolution of grating, which seriously limits the continuity, tunability, and TBP of the generated waveform. Furthermore, by changing the alternating current (AC) waveform of the driving signal to the sweeping laser, linearly or nonlinearly continuously chirped MMW pulse can be easily generated and switched. Using our scheme, linearly and nonlinearly chirped pulses with record-high TBPs (89-103 GHz/50 μs/7 × 10 5) are experimentally achieved. © 2009 IEEE.

A high-performance photonic sweeping-frequency (chirped) radio-frequency (RF) generator has been demonstrated. By use of a novel wavelength sweeping distributed-feedback (DFB) laser, which is operated based on the linewidth enhancement effect, a fixed wavelength narrow-linewidth DFB laser, and a wideband (dc to 50 GHz) photodiode module for the hetero-dyne beating RF signal generation, a very clear chirped RF waveform can be captured by a fast real-time scope. A very-high frequency sweeping rate (10.3 GHz/μs) with an ultra-wide RF frequency sweeping range (∼40 GHz) have been demonstrated. The high-repeatability (∼97%) in sweeping frequency has been verified by analyzing tens of repetitive chirped waveforms. © 2013 Optical Society of America.

We demonstrated a single-walled carbon-nanotube-deposited planar lightwave circuit (PLC) waveguide for fourwave-mixing (FWM)-based wavelength conversion. FWMis generated from the interaction between the propagating light through the PLC waveguide and the deposited carbon nanotubes (CNTs) on the overcladding-removed core of the waveguide. The third-order nonlinearity of the CNTs is originated from the interband transitions of the π electrons causing nonlinear polarization similar to other highly nonlinear organic optical materials. FWM-based tunable wavelength conversion of a 10 Gbit/s non-return-to-zero signal is achieved with a power penalty of 3 dB in the biterrorrate measurements. To our knowledge, this is the first demonstration of a CNT-technology-based device for integrated photonic applications. © 2010 Optical Society of America.

We demonstrate a passively Q-switched erbium-doped fiber laser using a carbon-nanotube-based saturable absorber via evanescent field interaction. The carbon nanotubes are deposited on a side-polished fiber by optically-driven deposition method. Since only the evanescent field of the propagating light interacts with carbon nanotubes in saturable absorber, the fiber laser can maintain a relatively high intra-cavity power and output pulses with energy of 81.3 nJ are obtained with a repetition rate of 70.4 kHz and a pulse width of 4.5 μs. © 2012 Elsevier Ltd.

We propose and demonstrate an all-fiber, dispersion-mapped, erbium-doped fiber laser with net normal dispersion generating dissipative solitons. The laser is mode-locked by a hybrid mode-locking mechanism consisting of a nonlinear amplifying loop mirror and a carbon nanotube saturable absorber. We achieve self-starting, mode-locked operation generating 2.75 nJ pulses at a fundamental repetition rate of 10.22 MHz with remarkable long term stability. © 2014 Astro Ltd.

Provided is a signal processing method including a step of acquiring a plurality of Stokes parameters related to polarization in which X polarization and Y polarization included in a dual-polarization phase-shift keying (DP-PSK) signal are defined as an x component and a y component, respectively, and a step of acquiring a two-dimensional constellation diagram by orthographically projecting coordinates defined by each of the Stokes parameters, in a Poincare sphere coordinate system, onto a plane including coordinates (0, 1, 0), (0, 0, 1), (0, 1, 0) and (0, 0, 1).

We propose a novel scheme of OTDM utilizing pulse position modulation, where optical null headers (ONH) are inserted between the signal pulses periodically to allow channel identification. The ONH also achieves in-band clock distribution through the generation of high contrast pilot tone on the signal power spectra, enabling baud-rate flexible clock recovery. Using the novel scheme, clock recovery with a timing jitter of less than 200 fs is achieved at different baud rates up to 344 Gbaud. We demonstrate stable clock recovery with channel identification in 344-Gb/s OTDM transmissions over dispersion managed 3-km SMF. © 2013 Optical Society of America.

We introduce current commercial applications of carbon-nanotube (CNT) photonic technologies. In particular, two key applications of CNT mode-locked lasers will be described: high-speed optical sampling using a long-wavelength, low-repetition rate femtosecond CNT laser and 3D high-precision profile measurement using a high-repetition rate CNT laser. © 2011 The Japan Society of Applied Physics.

We report on our recent progress on Si Mach-Zehnder modulators (MZMs) incorporating sub-100 μm slow-light photonic crystal waveguide (PCW) phase-shifters. In the standard MZM with a PCW in each of the arms, we study the power-dependent bit-error-rate (BER) characteristics at 10 Gb/s, and measure BER = 1 × 10-9 and 1 × 10-8 even with phase-shifter lengths of 90 and 50 μm, respectively. Furthermore, by exploiting the low-dispersion slow-light in the 90 μm device, we measure a spectral operating bandwidth of 16.9 nm and temperature tolerance between 19-124°C, where the eye pattern amplitude is consistent to within ±25%. In the device with a 90 μm PCW in only one of the MZM arms, designed for large-ng operation, we achieve BER = 1 × 10 -9 at 10Gb/s and also observed barely but open eye patterns at 25 and 40 Gb/s. © 2013 IEEE.
