Latest Patents
One of Ahmad's latest patents is for a multiple wavelength laser source. This invention presents a simple and flexible wavelength division multiplexing (WDM) laser source utilizing a loop erbium-doped fiber amplifier (LEDFA) configuration. The loop acts as both a mirror and an amplification medium. The laser cavity is constructed from the loop mirror and a series of fiber Bragg gratings (FBGs) that select the appropriate lasing wavelengths. The FBGs can be arranged in parallel or in series at the output of the loop configuration. Optical attenuators are strategically placed in front of the FBG to manage the flatness of the laser source output and establish the necessary lasing conditions for each wavelength, thereby preventing competition among different lasing wavelengths. This configuration allows for the addition of multiple wavelengths as long as sufficient amplified spontaneous emission (ASE) is generated in the loop, achieving a signal-to-noise ratio as high as 55 dB.
Another notable patent involves an optical amplifier with a loop mirror filter noise reducer. This invention aims to minimize amplified spontaneous emission noise in the output signal of an amplifier, such as an erbium-doped fiber amplifier. The amplified signal is filtered using a loop mirror filter, which consists of a 3-dB fiber coupler with a loop of linear active fiber connected between two of its ports. The amplified and filtered signals can be extracted from one of the other ports, typically using a circulator.
