An analysis of the influence of thermal effects on the tuning behavior of a three-electrode distributed-feedback (DFB) laser is presented. In the adopted three-dimensional model, nonuniform injected current distribution is taken into account. The ele

The integration of history into educational practice can lead to the development of activities through the use of genetic 'moments' in the history of mathematics. In the present paper, we utilize Oresme's genetic ideas - developed during the fourteen

Long-wavelength vertical-cavity surface-emitting semiconductor lasers are investigated and heating effects on the light vs. current characteristics of VCSELs are analyzed by thermal-electric, optical, and electronic modeling. The model includes nonun

In this paper, a detailed analysis of the transient heat flow in a VCSEL is carried out. The transient thermal response of VCSEL axisymmetric structures is calculated based on a Green's functions method to solve the time- dependent thermal conduction

The effect of four seasonally changing and two static light photoperiod regimes was investigated in two populations of rainbow trout, Oncorhynchus mykiss shasta and kamloops (Walbaum), kept under almost constant temperature, diet and management from
