Phase-locked arrays of antiguides: analytical theory

Closed-Form Analytical Equations to Transient Analysis of Bang-Bang Phase-Locked Loops

Due to the nonlinear nature of the Bang-Bang phase-locked loops (BBPLLs), its transient analysis is very difficult. In this paper, new equations are proposed for expression of transient behavior of the second order BBPLLs to phase step input. This approach gives new insights into the transient behavior of BBPLLs. Approximating transient response to reasonable specific waveform the loop tran...

Supermode analysis of phase-locked arrays of semiconductor lasers: erratum.

The optical characteristics of phase-locked semiconductor laser arrays are formulated in terms of the array supermodes, which are the eigenmodes of the composite-array waveguide, by using coupled-mode theory. These supermodes are employed to calculate the near fields, the far fields, and the difference in the longitudinal-mode oscillation wavelengths of the array. It is shown that the broadenin...

Phase-locked laser arrays through global antenna mutual coupling

Phase locking of an array of lasers is a highly effective method in beam shaping because it increases the output power and reduces the lasing threshold. Here, we show a conceptually novel phase-locking mechanism based on ‘antenna mutual coupling’ in which laser elements interact through far-field radiations with definite phase relations. This allows a longrange global coupling among the array e...

Phase-locked Laser Arrays Revisited - IEEE Circuits and Devices Magazine

n January 1986 a review article on T phase-locked arrays of diode lasers was published in this magazine. Now, more than a decade later, major breakthroughs have occurred, both in theory and experiment, that have allowed phase-locked arrays to meet their promise of reliable, highcontinuous-wave (CW) power (= 0.5W) operation in diffraction-limited beams as well as multiwatt (5-10 W) near-diffract...
