Dry--etched short--cavity ridge waveguide MQW lasers suitable for monolithic integration with direct modulation
bandwidth upto 3 GHz and low drive currents.
Study 2 will use functional magnetic resonance imaging to test the hypothesis that the non-motivational effect of interest on learning is produced by the direct modulation
of striatal reward system in the hippocampal memory system.
Optical light sources with direct modulation
(irrespectively on source type) were more tolerable for in-band crosstalk penalty compared with an externally modulated DFB-LD source .
These include antioxidant and anti-inflammatory properties as well as direct modulation
of signalling pathways relevant for neurodegeneration.
The direct modulation
scheme is simple but suffers from a laser--frequency chirp effect, this chirp effect results in severe degradation of the RoF system performance.
The IP also provides carrier and image suppression when used with direct modulation
Sumitomo Electric Industries Ltd, a leader in optical solutions, has announced that it is expanding its 10 Gbps portfolio with the introduction of an integrated direct modulation
laser diode (DML) and a built-in electronic dispersion compensation (EDC) feature for use in 80 km transceivers.
One limitation in pursuing direct modulation
architectures for future wide-bandwidth-generating designs is the low knee frequency exhibited by devices that target this approach.
This article focuses on a special phase-locked loop (PLL) module used in a W-CDMA mobile terminal with an RF direct modulation
transmitter and a superheterodyne receiver.
These include inhibition of gastric secretions, which would slow digestion; enhancement of nitric oxide synthesis, which could alter insulin-stimulated glucose uptake; and direct modulation
of insulin secretion.
2+] release from intracellular stores) and by direct modulation
of calcium conductances, or indirect modulation of other ionic conductances which results in transmembrane hyperpolarization.
