Abstract :
A two-port microdisk laser connected to two radial waveguides is investigated using two-dimensional finite-difference time-domain methods for realising single transverse mode lasing with a heptagonal mode field distribution. Based on the experimental results, it is found that two-port microdisk lasers at the proper angles are easier to realise single transverse mode lasing compared with the one-port microdisk laser.
