This paper presents the mechanical design, analysis, fabrication, and testing procedures of a new large-range microgripper which is based on a flexible hinge structure. The uniqueness of the gripper is that the gripper arms not only provide large gripping range but also deliver approximately rectilinear movement as the displacement in nonworking direction is extremely small. The large gripping ...

In Malaysia, fiber cable is commonly installed underground or overhead. Once optical fibre cable is installed either underground or over-head, there is no physical maintenance implemented. The only maintenance on fibre cable is the monitoring of optical fibre attenuation. Bend loss affects the attenuation and any bending cable that contributes to the bend loss remains unmaintained since there i...

This paper shows the results of research on the optical control of a GaAs chip monolithic amplifier, and is an extension of previous work by our group in the field of optical-microwave interaction [1-3]. The amplifier was originally designed for the transmitter stage of an indoor mobile communications system in the 2.4 GHz band. The possibilities of optical control of this amplifier are evidenc...

Abstract A fiber Bragg grating (FBG) sensor system using a fiber ring laser with a hybrid amplifier is proposed and demonstrated. The hybrid amplifier comprises an erbium doped waveguide amplifier and a semiconductor optical amplifier. The experiment shows that such the hybrid amplifier has a high amplifier spontaneous emission power and gain spectrum. Moreover, this fiber ring laser can provid...

We experimentally demonstrate that a type-II pulsed optical parametric amplifier operated in a phaseinsensitive configuration works as a near-perfect classical optical amplifier whose noise figure approaches 3 dB at high gains. We further demonstrate that, when operated in a phase-sensitive configuration, this amplifier works as a quantum-optical amplifier whose noise figure goes below 3 dB and...

We present measurements of the power noise due to optical amplification in a Nd:YAG free-space traveling-wave amplifier as the amplifier transitions from the linear regime into the heavily saturated regime. The quantum noise behavior is demonstrated by saturating the gain of a 100-W class zigzag slab amplifier with a high-power beam and measuring the power noise detected by a single-spatial-mod...

Stimulated Brillouin scattering (SBS) is a recent technique developed to generate slow light in optical fibres. It is the simplest and most applicable method of slow light production. In this paper a high power laser pump was used to provide the Brillouin gain of a low power signal of -10 dBm. Three single mode fibres namely, standard fibre (STD), large area fibre (LA) and reduced slope fibre (...
