摘要： A passive interface circuit for coupling an output signal from a power amplifier to a load is disclosed. The interface presents an impedance to the power amplifier that increases as the power level in the output signal decreases. In one embodiment, the interface circuit includes a fixed network and a capacitor having a capacitance that varies with the potential across the capacitor. The fixed network couples the output signal to the load. The capacitor is connected in parallel with the load and has a capacitance that increases in response to an increase in potential across the capacitor. The capacitor is preferably a MEM capacitor having plates that move with respect to one another in response to changes in the average potential difference between the plates.

摘要： The output power of a signal generated by a mobile communications device is measured over a short period of time (e.g. one signal burst), and the data modulation carried by the signal is also determined. The measured power value is adjusted to compensate for variations due to the content of the data modulation. This enables the long-term average power output by the device to be determined more quickly than by averaging the power measured over many successive signal bursts.

摘要： The present invention relates to a wavelength-selective distributed Bragg reflector (DBR) device (5) which may be used in wavelength-selective optoelectronic devices (1) such as a tuneable semiconductor laser device or a tuneable wavelength-selective receiver. The device (1) comprises a semiconductor substrate and a plurality of semiconductor layers deposited upon the substrate that form a plurality of adjacent distributed Bragg reflector (DBR) components (5A-D). Each DBR component (5A-D) has: an elongate optical waveguide (11A-D) for carrying optical radiation (27), each waveguide (11A-D) being spaced laterally from adjacent waveguides with respect to the length of each waveguide (11A-D); and a DBR grating for selecting the wavelength (λ A-D ) of the optical radiation (27) carried by the waveguide (11A-D), the grating having along the length of the waveguide a grating pattern (38) of alternating strips of varying refractive index, each strip extending at a transverse angle (β) to the length of the waveguide (11A-D), and the strips of each grating pattern (38) being aligned with corresponding strips in each adjacent component. The strips of the DBR components (5A-D) extend at different transverse angles (β A-D ) to corresponding strips in other DBR components (5A-D) so that the DBR gratings of different DBR components (5A-D) select different wavelengths (λ A-D ).

摘要： Disclosed is a power detection device (11) for determining a polarization extinction ratio (PER) for aligning a polarization maintaining optical fiber (PMF) to an optical source providing a linear polarized optical signal. The power detection device (11) comprises a polarization signal splitting device (26), whereby the optical signal transmitted by the fiber (16) is split into a parallel polarized signal component (28) having a signal power value (P p ) and perpendicular polarized signal component (29) having a signal power value (P s ), which are measured by measuring elements (31,32). The polarization extinction ratio is derived from the determined signal power values P s and P p . If this ratio is maximized, one of the two principal polarization axes of the PMF (16) is coincident with the linear polarization state of the optical source (36). This allows a maximal maintaining of the polarization state at the end of the fiber.
