We have observed far-infrared radiation from an array of hot quasi-one-dimensional wires in GaAs. The wires have 6000 Å period with 3000 Å lithographic width. Spectroscopy of the infrared emission with a bolometer detector filtered by a magnetic field-tunable InSb cyclotron resonance wedge reveals: an intersubband plasmon resonance at 45 cm-1, and a measure of the resonance linewidth and electron temperature as a function of pulse current. The total intensity of the infrared signal yields a confirming measure of the temperature of the electrons, ranging from 6.0 to 12.1 K for currents of 40 nA to 2 μA per wire.
