We have carried out a magneto-optical investigation of the 2D electron gas in the extreme quantum limit. The measurements were made on modulation-doped GaAs-(AlGa)As multiple quantum well structures. A novel fiber-optic apparatus allows simultaneous transport and optical measurements in conjunction with He sup 3 refrigerators and high field (B
