Latest Patents

One of his latest patents is the Photonic D/A, which is an all-optical combined serial-to-parallel and digital-to-analog converter utilizing standard WDM technology. This system is based on bit interleaving and cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA). The optical system can operate on multiple-bit digital words at a very high bit rate. The analog output forms a series of pulses, with the amplitude of each pulse taking one of the eight discrete values. A low pass filter may be used to convert this bit stream into a continuous waveform, thus generating arbitrary waveforms. Unlike many current digital-to-analog converter designs that double in size with each additional bit, Siahmakoun's design allows for linear growth in components, making higher bit systems practical.

Another significant patent is the Shape Memory Alloy MEMS Heat Engine. This microelectromechanical systems (MEMS) based heat engine is capable of converting thermal energy gradients into mechanical or electrical energy. The design consists of a stressed oscillating beam formed from a shape memory alloy (SMA) thin film. As the temperature of the beam changes, its shape alters due to the phase transformation of the shape memory alloy, causing it to oscillate between a hot source and a cold source. The hysteretic behavior of the phase transformation enables the oscillating SMA cantilever beam to produce a net mechanical work output, which can be converted to electrical energy or mechanically linked to other MEMS devices.
