In order to address the challenge of increasing data rates, next generation optical communication networks will require the co-integration of electronics and photonics. Heterogeneous integration of these technologies has shown promise, but will eventually become bandwidth limited. Faster monolithic approaches will, therefore, be needed, but monolithic approaches using complementary metal-oxide-semiconductor (CMOS) electronics and silicon photonics are typically limited by their underlying electronic or photonic technologies. Here, we report a monolithically integrated electro-optical transmitter that can achieve symbol rates beyond 100 GBd. Our approach combines advanced bipolar CMOS with silicon plasmonics, and addresses key challenges in monolithic integration through the co-design of the electronic and plasmonic layers, including thermal design, packaging, and a nonlinear organic electro-optic material. To illustrate the potential of our technology, we develop two modulator conceptsan ultra-compact plasmonic modulator and, alternatively, a silicon-plasmonic modulator with photonic routing -both directly processed onto the bipolar CMOS electronics.

“…Analysis on direct modulation is carried out, varying different parameters, i.e., current (1310 nm In this study, VCSEL modulation optimization was done at different fiber lengths (by using fibers of different length) and the Chromatic dispersion effects (transmission at different windows for a G655 and G652) were determined. The reader is referred to [5] and [6] for other experimental setups that could be used.…”

The overwhelming increase in bandwidth demand as the number of people with smart phones and other internet-using gadgets shoots up, with emerging numerous apps (some with an aspect of live streaming), social media platforms, the increase in number of broadcasting networks both Radio and television stations, plus almost every household having a TV set and Radio, with a current advancement of access on mobile phones has created a bottle-neck in telecommunication transmissions. The blocking/denying internet access for specific apps has become the desperate measure users have resorted to, for example 'setting up a firewall for smart phones' to maintain fast internet, which is inconveniencing and user unsatisfying. Other measures in place include recent digital migration, which arose out of the Regional Radio communication Conference of 2006 (RRC06) and the subsequent Geneva 2006 Agreement (GE06) of the International Telecommunication Union (ITU) 'Recommendations' which resolved that all countries signatory to the agreement must migrate from analogue to digital broadcasting services by 2015 (Uganda was part). This is a smart move, but it doesn't solve the problem of increased required capacity. In this study, we experimentally demonstrate 10Gbps data transmissions using a direct data modulator that is, a 1300 nm Vertical Cavity Surface Emitting Laser (VCSEL). We characterized the modulator to attain effective performance thus obtaining the appropriate current value (5.5mA) at which we incurred minimum penalties and corresponding Bit Error Rates (BERs) favourable for high-speed modulation, i.e., a sensitivity of -16.8745 dBm power penalty was obtained on a 17km length ITU-T G.652 Non-Dispersion Shifted Single mode fiber.

In this paper, a small signal analysis of a Vertical Cavity Surface Emitting Laser (VCSEL) under the parasitic condition is developed. The analysis is based on the transfer function of the considered device under the parasitic case. The dominant pole approximation scheme is used for the reduction of its characteristic equation. The Convolution Theorem is also applied to get the temporal response. All interesting parameters are outlined. The effect of parasitic cutoff frequency is also analyzed. The results show that when the parasitic cut off frequency is lower than the damping rate, the device behaves like first order low pass filter, while it behaves like second order low pass filter when the parasitic cut off frequency is greater than the damping rate. On the other side, the device operates very fast towards the second order low pass filter and up to a peak power within 1.2 ns if the resonance frequency is increased to 2 GHz, so it can be exploited in very high speed optical systems.
