High performance tunable and multi-wavelength laser sources for phased array antennas

Abstract

Photonic true time-delay technique provides weight, size, EMI/EMP and cost advantages for constructing squint free phased array antennas. The photonic true time-delay networks demand high performance, high reliability wavelength tunable and multi-wavelength laser sources. This paper reports the hermetically sealed rapid-tuning tunable lasers and ultra-stable multi-wavelength laser diode and fiber laser sources. These devices have narrow linewidth, low intensity and phase noise, high side-lobe suppression, etc.
