We report a dual-band-swept, Fourier domain mode locking (FDML) laser with sweeping rate of 97.6 kHz. The laser uses a custom-designed dual-channel driver to achieve synchronization between two tunable filters. It is the first time to achieve simultaneous dual-band FDML laser. © 2012 Optical Society of America OCIS codes: (300.6360)Spectroscopy, laser; (140.4050) Mode-locked lasers

Asynchronous ventricular pacing has been shown to increase the risk of development of atrial fibrillation (AF) because of various mechanisms: retrograde atrioventricular (AV) conduction with increase in atrial pressure causing acute atrial stretch and reverse flow in the pulmonary veins, mitral regurgitation, reduced coronary blood flow, adverse neuroendocrine reactions, etc. Dual-chamber pacin...

A fully integrated dual-mode frequency synthesizer for GSM and Wideband CDMA (WCDMA) is presented. The synthesizer is designed to maximize hardware sharing between the two modes by applying fractional frequency synthesis to GSM mode and integer frequency synthesis to WCDMA mode. The shared components include phase frequency detector (PFD), charge pump (CP), loop filter, integer frequency divide...

Dual-mode square patch resonator is well known in the design of a single band quasi-elliptic bandpass filter response. Here, the dual-mode square patch resonator is employed to achieve a dualband bandpass filter. A 6 pole dual-band bandpass filter response with 3 poles at each passband will be presented. The dual-band filter also exhibits a transmission zero between the two passbands. A detaile...

A diversity monopulse antenna is presented in this paper. This monopulse antenna is based on a dual frequency dual mode ratrace coupler that has been designed by using Composite Right/Left Handed (CRLH) Transmission Lines (TL). The device has two input ports while the (Σ) and (Δ) outputs are interchangable at either of the two operating frequencies. In this way the monopulse antenna can work at...

A novel perturbation approach using additional metalized via-holes for implementation of the dual-band or wide-band dual-mode substrate integrated waveguide (SIW) filters is proposed in this paper. The independent perturbation on the first resonant mode TE101 can be constructed by applying the proposed perturbation approach, whereas the second resonant mode TE102 is not affected. Thus, new kind...

We report on stable dual-wavelength operation in passive and hybrid mode-locking of a 10GHz two-section InAs/InP(100) quantum dot laser diode operating at 1.5μm. The range of stable passive mode-locking, the locking range of hybrid mode-locking and detailed measurements of the phase modulation in the output pulses will be presented.
