Interband cascade lasers emitting optical frequency combs in the midwave infrared at wavelengths around 3.3 micrometer are promising sources for applications like dual comb spectroscopy probing strong fundamental absorption lines of numerous chemical and biological agents [Bagheri et. al. Sci. Rep. 8(1) (2018), 3322]. In this contribution, the intermode beat frequency (IBF) tuning range and IBF line width of an 4 mm long optical frequency comb interband cascade laser subject to single cavity optical self-injection is investigated experimentally and by modelling [Drzewietzki et al., Opt. Express 21 (2013), 16142].
