In all trials, both measured forces spiked sharply upon end face contact. The optical power throughput plateaued for an insertion distance of nearly 2 mm before decreasing due to fiber bending outside of the capillary. This plateau corresponded to insertion losses as low as 0.12 dB, and was typically below 0.3 dB. Our results show that these force spikes strongly coincided with the maxima in optical power; meaning that forces measured in this way can be used as an indicator during construction of low insertion loss mechanical fiber optic splices. Future work involves adapting our apparatus to automatically halt motion when the force spikes are detected, making similar measurements using multimode optical fibers, and miniaturization for transition towards fielding this unit as support equipment.

Substrate-transferred crystalline coatings represent an entirely new concept in high-performance optical coatings. This technology was originally developed as a solution to the long-standing thermal noise limitation found in ultrastable optical interferometers, impacting cavity-stabilized laser systems for precision spectroscopy and optical atomic clocks, as well as interferometric gravitational wave (GW) detectors [1]. The ultimate stability of these systems is currently dictated by coating Brownian noise, driven by the excess mechanical losses of the materials that comprise the highly reflective elements of the cavity end mirrors. Compared with state-of-the art ion-beam sputtered dielectric reflectors, crystalline coatings, comprising substrate-transferred GaAs/AlGaAs heterostructures, exhibit competitive reflectivity together with a significantly enhanced mechanical quality, resulting in a thermally-limited noise floor consistent with a tenfold reduction in mechanical damping at room temperature [2]. Building upon this initial demonstration, we have recently developed high-performance crystalline supermirrors with parts-per-million levels of optical losses, including both absorption and scatter, at wavelengths spanning 1000 to nearly 4000 nm, with experimentally verified absorption coefficients below 0.1 cm-1 in the near infrared [3]. These advancements have opened up additional application areas including the focus of this work. Here we demonstrate the first implementation of crystalline supermirrors in an active laser system, expanding the core application area of these low-thermal noise cavity end mirrors to inertial sensing systems and specifically next-generation high-sensitivity ring-laser gyroscopes [4,5].

In this paper we demonstrated 9.978-GHz microwave extraction from a mode-locked Er-fiber laser with -113 dBc/Hz phase noise at 10 kHz offset frequency. Instead of phase locking loop or direct detection, the extraction was achieved by a delay-matched frequency conversion pair and IF-domain opto-electronic conversion and narrowband filtering. Phase noise suppression as large as 32 dB, compared with the LO, was achieved. Future advantage may include the simple carrier tuning by the external LO.

Commercial-off-the-shelf photonic components designed for datacenter or industrial applications do not typically satisfy the environmental ruggedness requirements of aerospace and military applications. In order to reduce costs and schedule risk for insertion of photonic components into these harsh-environment avionic and vehicle applications, we developed a variety of rugged photonic transceivers and media converter modules. We then performed qualification testing to demonstrate that these modules meet or exceed the requirements.

Detecting and analyzing the spectral content of intercepted microwave and millimeter-wave signals over a very wide bandwidth in real-time and with high resolution is an essential capability in many applications, ranging from commercial and surveillance, to defense. This is typically implemented by dividing the RF spectrum to be analyzed into narrower frequency slices, known as channelizing, which effectively sub-rates the input bandwidth and allows for signal processing in parallel with increased resolution [1].

We proposed to mitigate the effect of modal dispersion by reducing the effective NA of the fiber link. A simple spatial mode filtering technique has been experimentally demonstrated to improve the performance over a 30 m link, achieving a BER of 10-8 at 1 Gbps. This approach offers a simple and a cost-effective solution to deliver Gigabit Ethernet using NRZ signaling over short reach POF networks employing standard 1 mm SI-POF
