Photo-bleaching induced electro-optic polymer modulators with dual driving electrodes operating at 1.55 µm wavelength

Abstract: Electro-optic (EO) polymeric Mach-Zehnder (MZ) modulators with photo-bleaching (PB) induced waveguides and dual driving electrodes operating at 1.55 mm wavelength have been demonstrated. The halfwave voltage of the integrated polymeric modulator was 4.5 V in a push-pull configuration with a 1.5 cm interaction length. The extinction ratio was greater than 20 dB, and the fibre-to-fibre insertion loss was 8 dB for the TM polarisation. The achieved fibre-to-fibre insertion loss and driving voltage are the best, to… Show more

“…Chromophore concentration per unit area is given by J 0 ) N 0 L. The initial volumetric chromophore concentration N 0 is related to the chromophore:host weight ratio w, by N 0 ) wF/ MW, where F is the density of the host polymer, and MW is the molecular weight of the chromophore. 43 The host polymer in all cases considered here is APC, with F ) 1.2 g/cm 3 , and the chromophore concentration is 25 wt %, yielding w ) 25/75 ) 1/3. The chromophore-doped core layer thickness is L. The absorption coefficient R(λ b ) for all chromophores is obtained from their respective absorption spectra.…”

“…For the case of lasers and optically pumped amplifiers based on dyes, as well as for polymer electro-optic devices based on NLO chromophores, photobleaching due to the pump or input light source causes device performance to deteriorate with time. 1,2 On the other hand, photobleaching is very useful for patterning lowloss NLO polymer waveguides 3,4 and for postfabrication trimming of NLO polymer devices. [5][6][7][8] In the context of photobleaching being detrimental, there is great interest in estimating the photostability of the absorbing molecules.…”

“…2͑b͒, the maximum shift of the resonance wavelengths is about −9 nm, indicating that this photobleaching method is highly effective for the postfabrication trimming of ring resonators. 6,7 In this work, we model the photobleaching process to explain the trend in the observed resonance shift and refractive index change.…”
