In this paper, we present the design, simulation, fabrication, and some measurement and characterization of a novel 16-bit digital variable optical attenuator (VOA) that attenuates by switching individual mirror of an array as an attempt to achieve input voltage variation independence and output linearization. The design was aided by a simulation package that features coupled electrostatic and mechanical solver. The mirror array spans an area of 1500 1500 m 2 and contains 16 equal-length rectangular micromirrors. Each mirror is suspended by two torsion beams. Experiments on beam design and width variations are conducted. Assuming Gaussian distribution, the mirror widths computed by an iteration algorithm vary from about 40 to 250 m. Based on silicon-on-insulator (SOI) technology, two fabrication schemes to open the backside optical entrance were investigated . A hydrofluoric (HF) acid vapor-phase-etching (VPE)setup built to release the microstructure anhydrously is the key to achieve high yield especially for fragile components. Surface flatness, resonance frequencies, and tilt angles of selected mirrors were characterized. Quartz chips patterned with aluminum electrodes and 10 m-high SU8 spacer columns were fabricated and assembled to corresponding device chips. Optical performance adversely affected by mirror bending is believed to originate from the intrinsic stress of the SOI wafer.[1271]Index Terms-Deep reactive ion etch (DRIE), hydrofluoric (HF) vapor-phase-etching (VPE), micro mirrors, silicon-on-insulator (SOI), variable optical attenuator (VOA).

“…Many schemes of the wavelength-tunable Erbium-doped fiber lasers (EDFLs) operated at C-plus L-band have also emerged to meet the demand on testing C and L-band fiber-optic devices. Typically, the gain media such as the erbium-doped fiber (EDF) and the erbiumytterbium codoped double clad fiber [7], were employed to configure the L-band EDFLs in dual resonant cavity [8], linear overlapping cavity [9], and single ring cavity [10]. Different approaches for wavelength-tuning the EDFL with the intra-cavity Fabry-Perot filters [11], the fiber Bragg gratings (FBGs) [12,13] and the tunable-ratio optical coupler [14] were proposed.…”

“…This has compelled further research in increasing the L band gain and power conversion efficiency (PCE) values. The Cband seed signal injection [5]- [6] and re-reflection of backward amplified spontaneous emission (ASE) using circulator with fiber reflectors or fiber Bragg gratings [7]- [9] are some of the ways to increase the L band gain.…”

Abstract-Optical amplification in the C and L band region with wave division multiplexing can provide over 160 channels. The paper provides simulation studies of such a wideband erbium doped fiber amplifier which utilizes a tunable tap at the TLS source end. This isolates and provides two parallel channels for simultaneous amplification in both C and L band. Such a configuration has shown to provide a gain well over 20dB from 1525-1615nm bandwidth with an average noise figure of 10dB (approx.). Gain saturation effects beyond20dBm/channel signal level and, gain spectra at different pump powers and amplifier lengths have also been studied.
