Method and Apparatus for Transmitting Optical Signals

In the field of optical communication, there has always been a demand for efficient, low-power transmitters that can transmit optical signals without compromising quality or speed. High extinction ratios, which represent the difference in power levels between logical on (1) and off (0) states, are a key benchmark, with limitations in achieving these ratios posing a serious challenge. Current optical transmitters often struggle to achieve high extinction ratios while operating at low power levels. The best they can typically achieve is around 10 dB, and escalating the power utilization more often leads to thermal dissipation problems. A technology that can overcome the hurdle of achieving high extinction ratios with low-power signals is needed.

Technology Description

The optical transmitter technology provides an innovative solution for transmitting optical signals with higher-than-average extinction ratios using low-power drive signals. This advanced technology works at an impressive energy efficiency as it requires less than 20 mW of power. With the ability to operate at large data rates typically in the spectrum of Gbits/sec, it sets itself apart from others in the market. It also allows modulations with both low-power and low-fidelity drive waveforms. What primarily sets this technology apart is its capability to achieve an extinction ratio surpassing 20 dB, a feat typically not seen in current optical transmitters that often achieve a peak of around 10 dB. The technology's uniqueness lies not only in high extinction ratios but also in its use of conventional and quite often noisy high-speed, low-power electronics to generate high-extinction, high-fidelity optical waveforms. The invention is a major step forward in terms of reliable and efficient optical signal transmission.
