“…For dense WDM operation, the emission wavelengths have to be accurately controlled. Schemes based on interference [17] and referencing with a calibrated emission [18] were previously proposed. Optical power from the optical sources will also be monitored.…”

This paper proposes a new node architecture and protocol for a wavelength division multiple access (WDMA) packet-switched metropolitan area network. The network operates on a dual-bus topology and the tunable-transmitter and fixed-receiver scheme is adopted to facilitate data multiaccess. The network protocol runs on a cycle mechanism and the cycle length can be adaptively changed according to the data traffic, thus provides high throughput. The photonic implementation of the proposed network architecture and network nodes are discussed and a new packet-signaling scheme is proposed to avoid data collision during multiaccess. An experimental demonstration is also presented to show its feasibility.

“…In order to implement a linearly tuned TLS that is free from the influence of the nonidealities of PZT, such as non-linearity, hysteresis, creep, and environmental changes, a device capable of monitoring the frequency change of a light source is required. Candidates for frequency monitoring devices, which can supply wavelength references, include microwave modulators [5], gas cells [9], FBGs [10], fixed etalons [11], and diffraction gratings, as mentioned above. The devices chosen in this study were a fixed etalon and an FBG.…”

A method for a linearly swept tunable laser source with a simple configuration is proposed. The principle of the method is based on the fact that the interval of the transmission peaks of a fixed etalon can be used as a stable reference. The reference provided by the fixed etalon is used to deform the drive signal waveform for linear optical-frequency tuning. To verify the validity of the methodology, an optical system augmented with two fiber Bragg gratings, one fixed etalon, and a dedicated signal-processing circuit was built and experimentally tested, confirming that it works well for a linearly tuned tunable laser source. Moreover, the potential for extending the scope of the application of the proposed method is suggested and some ways to improve its performance are also discussed.

“…The most basic interferometer setup is the Michelson interferometer using two mirrors for the superposition of two light beams [ 1 – 2 ]. A related interferometric setup based on multi-beam interference in an optical cavity is the Fabry-Pérot interferometer typically used in form of an etalon in spectroscopy, lasers, and optical telecommunication [ 3 ] for precise wavelength selection within a certain free spectral range [ 4 ]. The Fabry–Pérot interferometer is characterized by the finesse , defined as the ratio between the spectral selectivity and the free spectral range [ 5 ].…”

SummaryInterferometric displacement detection in a cantilever-based non-contact atomic force microscope (NC-AFM) operated in ultra-high vacuum is demonstrated for the Michelson and Fabry–Pérot modes of operation. Each mode is addressed by appropriately adjusting the distance between the fiber end delivering and collecting light and a highly reflective micro-cantilever, both together forming the interferometric cavity. For a precise measurement of the cantilever displacement, the relative positioning of fiber and cantilever is of critical importance. We describe a systematic approach for accurate alignment as well as the implications of deficient fiber–cantilever configurations. In the Fabry–Pérot regime, the displacement noise spectral density strongly decreases with decreasing distance between the fiber-end and the cantilever, yielding a noise floor of 24 fm/Hz0.5 under optimum conditions.
