Colloidal quantum dot based light emitting devices on silicon substrate
… spectra which makes them an excellent choice for active media in optoelectronic applications. Moreover, solution processability of colloidal quantum dots makes processing and integration on the silicon platform easier. This thesis discusses the design and fabrication of colloidal quantum dot based …

Design method for ultimate efficiency in linear-cavity continuous-wave lasers using distributed-feedback
… derives the cavity analytically based on the active medium properties for the chosen pumping scheme. The method combines the general grating design equations, valid for both passive and active media, and the optimum signal power calculations. The idea that lies at the heart of the design …

Performance of four-stage cascaded fiber optical parametric amplifier (FOPA) using optisystem
… FOPA. A cascaded FOPA is a FOPA with two or more active media, commonly known as a highly nonlinear fiber (HNLF). Previous experimental work shows that the improvement in gain and bandwidth of the cascaded FOPA depends on the passive or active devices inserted in between the HNLF. However, the …
