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.
