Optical response of BiTeX (X = I, Cl, Br) semiconductors with a giant Rashba-type spin splitting is studied at low temperatures up to high magnetic fields applied in the Faraday configuration. Unlike the reflection configuration, the transmission configuration allows us to directly observe a set of inter-Landau level transitions in the vicinity of the crossing point of the conduction bands - Dirac point. Optical response of BiTeX compounds is compared with that expected theoretically, calculated using a simple Rashba-type Hamiltonian within Kubo-Greenwood formalism.
