We report on the characterization and validation of custom-designed 894.6 nm vertical-cavity surface-emitting lasers (VCSELs), for use in miniature Cs atomic clocks based on coherent population trapping (CPT). The laser relative intensity noise (RIN) is measured to be 1 × 10(-11) Hz(-1) at 10 Hz Fourier frequency, for a laser power of 700 μW. The VCSEL frequency noise is 10(13) · f(-1) Hz(2)/Hz...
A lasing charactrization of a Brillouin/erbium optical fiber laser (BEFL) is experimentally discussed. In the BEFL, an erbium-doped fiber amplifier (EDFA) is incorporated into the Brillouin laser resonator to enhance small Brillouin gain, which makes the configuration of the Brillouin laser resonator easy and flexible. The experimental results show that the output power of the BEFL has a thresh...
We had recently measured a chromatic dispersion of optical fiber and a time delay of chirped fiber grating based on a bidirectional modulation of an optical intensity modulator. In this paper, we analyze characteristics of the chromatic dispersion measurement method using a bidirectional modulation of an optical intensity modulator, and give a detailed explanation about the selection of measure...
Optical interconnects (OIs) continue to require more and sophisticated driver receiver electronics as higher baud rates are pushed in datacom, mainly due the bandwidth stagnation of optoelectronic components such vertical-cavity surface-emitting laser (VCSEL) transmitter well photodetector (PD) receiver. Another important focus is maintaining high energy efficiency for OIs. For both cases, a re...
Interband cascade lasers are semiconductor emitting in the mid-infrared domain but relying on interband transitions, contrary to their intersubband counterparts, quantum lasers. Our experimental study of relative intensity noise a multi-mode laser at 4.1 ?m shows that room-temperature structure exhibits relaxation frequency GHz range. We demonstrate that, far above threshold current, increases ...
