چکیده
In the present work, a new vertical cavity surface emitting laser (VCSEL) structure employing combined oxide layer and single defect photonic crystal index guiding layer has been investigated for L-band optical fiber application. The basic design goal was to obtain photonic crystal VCSEL (PhC VCSEL) with the high power, high slop efficiency and low threshold that operate at 1.55-1.6μm wavelength single mode region. By using the combination of photonic crystal and oxide layer, we have achieved high power VCSEL that operated fundamental mode. The influence of the hole etching depth of photonic crystal looking for the highest power and the lowest threshold current is also investigated.
