Lear, K. L. et al. Small and large signal modulation of 850 nm oxide-confined vertical-cavity surface-emitting lasers.
(For more information on the techniques of information compression, signal modulation, and multiple access, see telecommunications).
The theoretical analysis is based on strict derivation rather than small signal modulation.
We present ultrafast dynamics of lasers with direct signal modulation speeds in excess of 100 GHz.
The CW wavelength is launched into another FP-LD (the slave laser) for direct signal modulation.
Beam sizes are derived from the resulting Compton signal modulation measured by a downstream detector.
Consequently, strong absorption and low resonance Q factor result in performance restrictions such as shallow signal modulation depth, low absolute efficiency, and poor high-power durability.
In order to increase the sensitivity of the instrument, signal modulation by application of a high-voltage square wave across the sample is used.
This signal modulation triggered the reversible migration of cells into and out of the neurosphere, and also altered their spatial distribution in the aggregate (Fig. 4h).
(i) AM stations transmitting stereophonic programs not exceed the AM maximum stereophonic transmission signal modulation specifications of stereophonic system in use.
It is shown that the signal modulation is enhanced significantly at some particular wavelength values (optimum signal wavelength).
