2004 (English)In: Applied Physics Letters, ISSN 0003-6951, E-ISSN 1077-3118, Vol. 85, no 21, 4851-4853 p.Article in journal (Refereed) Published
We report on the performance and analysis of 1.3 mum range InGaAs/GaAs vertical-cavity surface-emitting lasers (VCSELs) with an integrated mode filter consisting of a patterned silicon layer on the top distributer Bragg reflector. In this way, 1 mW of single mode power is obtained from a device with a wavelength of 1265 nm and a threshold current of 2.6 mA at room temperature. An effective index model is used to extract the internal and external losses of the VCSEL structure and to predict the modal losses with and without mode filter, thereby providing a useful design tool for single mode VCSELs.
