“…Upon submersion, water diffuses into the cladding region and initially has no effect on the core refractive index; consequently, (2) may be written (3) The sign of the wavelength shift therefore depends on the relative magnitude of the two terms in the brackets. In [17], the first term, which describes swelling is measured at approximately for maximal water uptake, while the second term is approximately two orders of magnitude higher [18]. Consequently, the second term dominates and, since for this fiber is negative [9], there is an initial positive wavelength shift.…”

Abstract-A long period grating was photoinscribed step-bystep in microstructured poly(methyl methacrylate) fiber for the first time using a continuous wave HeCd laser at 325 nm, irradiating the fiber with a power of 1 mW. The grating had a length of 2 cm and a period of 1 mm. A series of cladding mode coupling resonances were observed throughout the spectral region studied of 600 to 1100 nm. The resonance wavelengths were shown to be sensitive to the diffusion of water into the fiber.Index Terms-Humidity, long period grating, microstructured polymer optical fiber (mPOF), optical fiber sensor, photonic crystal fiber (PCF).

“…Various polymeric thermo-optic switches have been reported including digital optical switches (DOS), Mach-Zehnder interferometer switches, directional coupler switches, multimode interference/vertical coupler switches, and TO total-internal-re°ection switches. [14][15][16] Watanabe et al 17 reported a digital 1 Â 2 TO switch using waveguide silicone resin. The digital TO switches were characterized at 1.55 m. The power consumption and insertion loss of the transmission port were 130 mW and less than 2.5 dB, respectively.…”

A chromophore molecule-linked azo polymer as waveguide material (MCAP) of polymeric thermo-optic digital optical switch (DOS) was prepared with a chromophore molecule (ABFA), a polyether polyol and isophorone diisocyanate (IPDI). The chemical structures of ABFA monomer and azo polymer MCAP were characterized by FT-IR and UV-Visible spectroscopy. The thermal and mechanical properties of the MCAP¯lm were investigated. The refractive index and transmission loss of MCAP¯lm were measured at di®erent temperatures and different laser wavelengths by an attenuated total re°ection (ATR) technique and CCD digital imaging devices. A polymeric thermo-optic DOS based on the thermo-optic e®ect of the MCAP was designed and the performance of the switch was simulated by using the¯nite di®erence beam propagation method (FD-BPM). The experimental results showed that the power consumption of the polymeric thermo-optic switch could be only 0.64 mW, while the response time of the switch could be as short as 3.0 ms.

“…The thermal inertia prevents the effective index changes from being almost instantaneous, and the diffusion of heat may prevent a precise control of the optical properties in some structures. Fine control of the temperature of the device by means of Peltiers has been used to tune phased-array WDM devices [12][13][14] with dimensions of the order of tents of mm and very low time responses (in the best case in the order of ∼ 2 ms). Thermo-optical phasedarray WDM devices with individual addressing of each WGs have also been proposed [15,16].…”

Abstract:We demonstrate compact tunable phased-array wavelengthdivision multiplexers driven by surface acoustic waves (SAWs) in the low GHz range. The devices comprise two couplers, which respectively split and combine the optical signal, linked by an array of single-mode waveguides (WGs). Two different layouts are presented, in which multi-mode interference couplers or free propagating regions were separately employed as couplers. The multiplexers operate on five equally distributed wavelength channels, with a spectral separation of 2 nm. A standing SAW modulates the refractive index of the arrayed WGs. Each wavelength component periodically switches paths between the output channel previously asigned by the design and the adjacent channels, at a fixed applied acoustic power. The devices were monolithically fabricated on (Al,Ga)As. A good agreement between theory and experiment is achieved.
