The joint authors of this comprehensive paper are all British, and have been employed on Standard Communication Laboratories on variable frequency multipliers for periods ranging from 10 to 25 year
Quantum-cascade distributed-feedback lasers with high-power, continuous-wave (cw), tunable, single-mode emission are reported. The emission wavelengths are near 5.2 and 7.95 mu m.
planar, fully gain guided tapered lasers deliver 1.5 W CW, with M2 = 1.6, T0 = 143 K and a slow axis divergence of only 1.3ð FWHM and 2.4ð at 1/e2.
Index-guided tapered lasers at 975 nm deliver 1 W CW, with a low M2 of 1.6 at 1/e2, which is a record for such a device, no measurable astigmatism, and a narrow far-field angle of 6.8deg FWHM.
We report the demonstration of high-power and low relative intensity noise (RIN) directly modulated distributed feedback lasers at 1.55 μm.
We describe for the first time to our knowledge the performance for a linear array of tapered laser diodes with both fast- and slow-axis collimation using a microlens for fast-axis collimation and
We propose a low-complexity and high-precision symbol synchronization algorithm based on dual-threshold amplitude decision for FPGA-based real-time Intensity Modulation Direct Detection (IMDD) OFDM
This paper describes an apparatus for performing high-precision electrical and thermal characterization of thermoelectric modules (TEMs).
There is a straightforward algorithm for computing the transitive closure of an n-node graph in 0(log sup 2 n) time on an EREW-PRAM, using n sup 3 /log n processors, or indeed with M9n) log n proce
IC-compatible microelectromechanical intermediate frequency filters using integrated resonators with Q's in the thousands to achieve filter Q's in the hundreds have been demonstrated using a polysi
