TLDR
In this paper, the feasibility of realising a high-order LC filter with a small set of different capacitor values, without sacrificing the frequency response specifications, is indicated, and this idea could be conveniently adopted in other filter structures also, for example the FDNR transformed filter realisations.Abstract:

Surface emitting lasers
TL;DR: In this article, the authors review the concept of a vertical-cavity surface-emitting laser, mainly consisting of the GaInAsP/InP, GaAlAs/GaAs, and GaInA/GaA systems, and their ultimate performance and impact on the electronics industry is discussed.

FILSYN—A general purpose filter synthesis program
TL;DR: A very general computer program is described that can be used for the synthesis of passive LC, active RC, and (infinite impulse response) digital filters, which offers many firsts, including the passive realization of complex quadruplets of transmission zeros.
