    "abstract": "The integration of a double barrier resonant tunneling diode within a\nunipolar optical waveguide provides electrical gain over a wide bandwidth. Due\nto the non-linearities introduced by the double barrier resonant tunneling\ndiode an unipolar InGaAlAs/InP optical waveguide can be employed both as\noptical modulator and optical detector. The modeling results of a device\noperating as optical modulator agree with preliminary experimental data,\nforeseeing for an optimized device modulation depths up to 23 dB with chirp\nparameter between -1 and 0 in the wavelength range analyzed (1520 nm - 1600\nnm).",
