We demonstrate a clear eye-diagram at 36 Gb/s of a BiCMOS driver directly wire-bonded to an InP electro-absorption modulator (EAM) both fabricated through foundry platforms. The driver is fabricated in a 0.25 μm SiGe:C BiCMOS technology and delivers a maximum of 2 Vp-p amplitude when single-ended. The driver is DC-coupled to the modulator, simplifying the electronic-photonic assembly. The EAM operates in the L-band at 1590 nm, with a DC bias set at –1.6 V for on-off keying non-return to zero modulation. We measure the operation from 10 to 40 Gb/s, recording the dynamic extinction ratio from 5 to 3 dB, respectively. The use of foundry platforms does not require any fabrication process change and offers a wide spectrum of high-performance photonic-electronic integrated circuits.

We review digital methods to mitigate the Kerr nonlinearity in multi-mode and/or multi-core fibres operating in different operational regimes as determined by differential mode delay and linear mode coupling. The results demonstrate that transmission performance can be more than doubled for feasible fibres characteristics.

Hollow-core fibers have demonstrated record performance in applications such as high-power pulse delivery, quantum computing, and sensing. However, their routine use is yet to become reality. A major obstacle is the ability to maintain the polarization state of light over a broad range of wavelengths, while also ensuring low attenuation and single-mode guidance. Here we simulated, fabricated and characterized a single-mode polarization-maintaining anti-resonant hollow-core fiber. The birefringence was achieved by introducing resonators of different thicknesses, thereby creating reduced symmetry in the structure. The measured group birefringence of 4.4x10-5 at 1550 nm is in good agreement with the calculated group birefringence from the simulations. This corresponds to a phase birefringence of 2.5x10-5 at 1550 nm. The measured loss of the fiber was 0.46 dB/m at 1550 nm. With its simple structure, low loss, and broadband operation this polarization-maintaining anti-resonant hollow-core fiber is a serious contender for applications in gas-based nonlinear optics and communications.

We present the first realization of strain sensing in a multimode OM4 optical fiber using phase-sensitive optical time-domain reflectometry. We demonstrate that single mode operation in an OM4 fiber is achievable and allows the fiber strain to be measured in a distributed manner. The 4 km of OM4 fiber is effectively measured with 20 cm spatial resolution which proves that coherent Rayleigh scattering based techniques can be used to interrogate multimode optical fibers.
