Definitions
- the present invention is directed to wavelength tuning of passively athermalized wavelength division multiplexer or demultiplexer devices, more particularly of phased array (phasar) devices.
- the present invention applies to devices athermalized by the use of an organic material (for example, polymer) with negative variation of refractive index vs. temperature (i.e., dn/dT).
- the present invention uses the property of organic materials to change their refractive index upon exposure to suitable- wavelength radiation, in order to finely tune the channel wavelengths of multiplexer or demultiplexer devices.
- the channel wavelengths can be roughly tuned by choosing the appropriate input and/or output ports by routine methods well known to the skilled artisan.
- the organic material is then exposed to appropriate radiation in small incremental steps in order to tune its index and, thus, the channel wavelengths.
- the refractive index of copolymer epoxy 17 is 1.43 at 1550 nm wavelength, 22 C, and the refractive index variation vs. temperature (dn/dT) is -3 x 10 "4 °C "1 at 1550 nm in the range 22-73 °C.
- the polymer material comprises a copolymer referred to herein as "Copolymer epoxy 26.”
- Copolymer epoxy 26 is prepared by polymerizing about 9 wt.% 15FON about 73 wt.% 5FBA, about 9 wt.% 6FPA, and about 9 wt.%) GMA.
- UV -induced index change of the polymer used in this example was measured for calibration purposes.
- Planar polymer layers of the copolymer epoxy 10 described above were deposited on silica substrates by spin-coating.
- the polymer composition was 55 wt.% trifluoroethylmethacrylate, 35 wt.% pentafluorostyrene, and 10 wt.% glycidyl methacrylate.
- the polymer was deposited by spin-coating from a solution (35 wt.%> polymer, 65 wt.% ethyl acetate), although any known technique can be used.
- the polymer layers were exposed to UV radiation using a commercial UV lamp with a maximum emission between 240 and 320 nm ("H lamp").
- the lamp power was 190 W.cm “1 (power density x irradiated area length) and the conveyer speed was 1.5 cm.s "1 , providing an energy density per pass of 127 J.cm " .
- the absorption of the polymer (optical density) is shown in Figure 1. The absorption band at 260 nm is located in the emission spectrum of the lamp, enabling photo-induced changes in the polymer.
- a phased array demultiplexer consisting of a silica substrate, a doped silica waveguide circuit core and a polymer overclad was prepared using standard techniques well known to the skilled artisan.
- a commercial core layer supported on a silica substrate was used.
- the nominal core layer composition was (in wt.%): GeO 2 13.9, P 2 O 5 1.4, B 2 O 3 3.4, and SiO 2 81.3.
- a step of 0.8 nm could be gained by shifting the channels by one output waveguide, such as by using the output waveguides #6 to 13 rather than #5 to 12. There remained a -0.22 nm wavelength difference to be compensated by UV irradiation.
- the phased array device was exposed to UV irradiation from the substrate side, in order to obtain a faster compensation, and also a better confinement of light in the waveguide after UV exposure.
- Such procedure can be used for planar substrates that are transparent to radiation.
- the exposure can be made from the polymer side provided the penetration depth is not too small as compared to the total polymer thickness.
- the phased array device was exposed to 2 passes under the UV lamp, under the same conditions as described above.
