A detailed eigenmode analysis of diode laser phased arrays both at and above threshold condition is presented.
The mode coherence of adjacent and non-adjacent spectral modes of a passively mode locked quantum dash (QDash) semiconductor laser are deduced through radio frequency beat-tone linewidth measuremen
A theory of mode conversion and radiation losses of a guided mode in a dielectric slab was described in Ref. 1.
This paper contains a perturbation theory which is applicable to the scattering losses suffered by guided modes of a dielectric slab waveguide as a consequence of imperfections of the waveguide wal
1317 1318 THE BELL SYSTEM TECHNICAL JOURNAL, SEPTEMBER 1 9 5 9 paper the representations of the fields associated with the natural modes of propagation in helix waveguide and copper pipe are given.
In order to obtain optimum illumination at the aperture of a dualmode conical horn,1 as in the open cassegrain antenna, 2 it is necessary to control the relative amplitudes and phases of the TEn an
There has been much uncertainty about the optical quality required for the components in an optical transmission link.
Helix waveguide consisting of closely wound insulated copper wire covered with an electrically absorptive or reactive jacket (Fig.
In this paper we discuss mode conversion in a straight fiber which maintains its circular cross section but whose radius a(z) increases monotonically with the length coordinate z so that it passes
In mode-division multiplexed (MDM) transmission systems, mode coupling is responsible for inter-modal cross-talk.
