We describe the design procedure, optimization, and fabrication cycle of an index-pattern FP laser on an InP platform. The design parameters of the ridge and reflector (based on slots) are extracted through simulations. In addition, the performance of reflectors with varying slot widths is analyzed. Subsequently, the extracted parameters are used in a rate equation model to predict the performance of the laser in terms of its L $ - $ I characteristics and the sidemode suppression ratio (SMSR). Moreover, the simulated results are compared with the experimental characterization of lasers fabricated with estimated design parameters revealing that the index-pattern laser with 0.3 $\mu $m slot width delivers the best performance by demonstrating a threshold current of ∼30 mA and $\text{SMSR} > \text{30 dB}$. |
