We fabricate and investigate wavelength selective components utilizing channel plasmon polaritons (CPPs) and operate at telecom wavelengths: a waveguide-ring resonator-based add-drop multiplexer (WRR-ADM) and a compact (3.75-microm-long) Bragg grating filter (BGF). The CPP waveguides represent 0.5-microm-wide and 1.3-microm-deep V-grooves in gold, which are combined with a 5-microm-radius ring ...

In this paper, we demonstrate a novel all-fiber wavelength-tunable acoustooptic switch utilizing intermodal coupling in a two-mode fiber (TMF). Its all-fiber configuration consisting of a fiber acoustooptic tunable filter and a mode-selective coupler results in the low loss ( 2 dB) operation. The operating bandwidth 50 nm, the switching time of 40 sec, and the crosstalk of 20 dB were achieved. ...

We demonstrated a vertically coupled microring resonator (VCMRR) filter as an Add/Drop wavelength filter. However, the accuracy of center wavelength was not sufficiently high for dense wavelength division multiplexing (DWDM) systems. Thus, a UV trimming technique using a SiN (n=2.01 at λ=1.55 μm) ring core was previously developed. Although a wide center wavelength trimming range of −12.1 nm an...

We propose and analyze theoretically a trap-door optical buffer based on a coupled microrings flat-top add/drop filter (ADF). By tuning one of the microrings into and out of resonance we can effectively open and close the buffer trap door and, consequently, trap and release optical pulses. To attain a maximally flat filter we present a new design approach utilizing the concept of a white light ...

Reconfigurable optical add/drop multiplexers (ROADMs) can be classified into three categories based on their underlying switching technologies. Category I consists of a single large optical switch; category II is composed of a number of small optical switches aligned in parallel; and category III has a single optical switch and only one wavelength being added/dropped. In this paper, to evaluate...

The supply air from the airliner ventilation system is a mixture of outside air and recirculated air that passes through a high efficiency particulate air (HEPA) filter. The effectiveness of two commercial-available airliner cabin air filters were investigated under the laboratory-based measurement due to the practical restriction of airliner cabin filter test during usage. The filtration effic...
