“…The details of this experiment are contained elsewhere [13], however an equation can be written in the following form for the peaks in the interference pattern: (6) where a0 is the symmetry point in wavelength, N is the peak location, and 2N is the wavelength of the corresponding peak. A system of simultaneous equations for the three unknowns p , $2 ' and fl can then be solved.…”

Analog-to-digital converters (ADCs) are an essential component of digital receiver systems. Progress at advancing the electronic ADC modules has been very slow due in large part to the difficulties in fabricating the electronic circuitry required for very high resolution and high sampling rate converters. This slow progress has resulted in a bottleneck between the received analog signal and the digital signal processing system. Single or multiple analog signal down conversion stages are required in digital receivers to down convert the received analog signal to an intermediate frequency (IF) that can be processed by the electronic ADC.There has been much recent interest in the use of photonics for direct digitization of the analog signal at the received RF frequency thus eliminating the need for analog down conversion. This paper reviews some of the recent research advancements in photonic ADCs. We will especially focus on the development of a novel photonic ADC module that uses semiconductor saturable absorbers to perform the data quantization. We will also present recent results in the development of a mode-locked fiber laser used as the sampling source in this photonic ADC architecture.

“…[1] Many passive mode-locking techniques have been presented in the past operating both in normal and anomalous dispersion regimes. Recently semiconductor saturable absorbers in the form of bulk, multiple quantum well (MQW) or single quantum well -saturable Bragg reflector (SBR) have been used to mode-lock linear fiber cavities [2][3][4][5][6][7]. Complex Ginzburg-Landau equations have also been used to model mode-locked laser operation successfully [3,5].…”

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. 12a. DISTRIBUTION AVAILABILITY STATEMENTAPPROVED FOR PUBLIC RELEASE; DISTRIBUTION UNLIMITED. 12b. DISTRIBUTION CODE ABSTRACT (Maximum 200 words)This report describes the results of dispersion and nonlinearity experiments of the components required for the development of picosecond passively mode-locked fiber lasers. First, we will summarize the interferometric dispersion measurement technique and results for short lengths of fiber (< 1 meter). We measured dispersion of standard fiber at 16.9 +/-1.4 ps/nm and Er-doped fiber at 8.5 +/-1.6 ps/nm at 1550 nm. Next, we measured the group delay of three chirped Bragg gratings using a phase difference method and a tunable laser. These chirped Bragg gratings served as one of the mirrors in the linear fiber laser cavity. Finally, we measured the nonlinearity of five different multiple quantum well saturable absorbers using a z-scan technique. The saturable absorbers served as the mode-locking mechanism in the passively mode-locked fiber laser. The values of the nonlinear absorption ranged from 1 to 3 cm/W. We also measured the refractive nonlinearity of one of the MQW saturable absorbers to be about -4 x 10 cm/W.
