Equivalent Circuit Model of High-Performance VCSELs

Bou Sanayeh, Marwan ; Hamad, Wissam ; Hofmann, Werner (2020-01-18)

In this work, a general equivalent circuit model based on the carrier reservoir splitting approach in high-performance multi-mode vertical-cavity surface-emitting lasers (VCSELs) is presented. This model accurately describes the intrinsic dynamic behavior of these VCSELs for the case where the lasing modes do not share a common carrier reservoir. Moreover, this circuit model is derived from adv...

Small-Signal Analysis of High-Performance VCSELs

Hamad, Wissam ; Sanayeh, Marwan Bou ; Siepelmeyer, Tobias ; Hamad, Hassan ; Hofmann, Werner H. E. (2019-02-26)

In this paper, a comprehensive model to describe the small-signal modulation response of ultra-high performance single- and multi-mode vertical-cavity surface-emitting lasers (VCSELs), with modulation bandwidths exceeding 30 GHz, is presented. Traditionally, utmost simplified dynamic models are used to extract dynamic figures of merit from single-mode edge-emitting lasers. These methods are lat...
