    The goal of this project is to create a wireless optical communication system that operates at high frequencies (up to 3 GHz). The system will function by taking a digital electric input signal, converting it to a photonic signal, recovering the signal at the other end of a short distance (~1 foot) and converting it back into a digital signal. High Frequency Communications – An Introductory Overview - Who, What, and Why? Abstract: Over the past 60+ years the use and interest in the High Frequency (HF -> covers – 30 MHz) band as a means to provide reliable global communications has come and gone based on the.

    The conversion from high frequency/high speed electrical signals into light can occur in two general ways—applied directly to the power source of the lightwave emitter (e.g. photodiode), or indirectly, by manipulating the light beam. Simple Schemes Simple optical laboratory experiments often involve voice transmission or low rate digital File Size: 33KB. High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred metres).Frequency range: 3 to 30 MHz.

Weiner. Best Readings in Optical Wireless Communications Optical wireless communications (OWC) has witnessed a revival recently among researchers in both academia and industry. The main reason for this resurgence is the exhausted radio-frequency (RF) spectrum, which is getting too crowded to handle the increasingly high demand for data rates.

Under this resonance condition, when the upper state is populated with a sufficient number of photons coming from the pump laser via the optical fiber, these photons begin to split into the lower frequency photons of the lower state and the coherent phonons at the Ωsound = 21 MHz frequency (Fig 1, center).Cited by: 1.
