چکیده
The spectral behaviour of device 5-90 at a current of 10 mA, well into the multimode regime, is shown in Fig. 3. Even though higherorder modes contain various fractions of both polar&ations, the hndamental mode polarisation is still pinned to the [01 11 crystal direction with a similar suppression ratio as before. This indicates that the polarisation selection mechanism may be strong enough for applications such as high-speed data transmission.

Periodic Travelling Wave Photodetectors with Serial and Parallel Optical Feed Based on InP
In this work, monolithically integrated, periodic travelling wave photodetectors with parallel and serial optical feed for high-speed and high-power applications at 1.55 μm wavelength are developed and characterized. The studied photodetectors are based on discrete, miniaturized evanescently coupled p-i-n photodiodes, which are distributed along a coplanar waveguide and thus form a travelling w...

An optical hybrid design based on paired multimode interference couplers in silicon-on-insulator process is investigated. The device exhibits greater than 20 dB CMRR and low phase deviation (<10) over 30 nm in the C-band. The design eliminates the use of optical cross waveguides for integration with balanced photodetectors. Introduction Coherent detection scheme provides high spectral efficienc...

متن کاملTravelling wave distributed photodetectors with backward wave cancellation for improved AC efficienc - Electronics Letters
Conclusion: This work has found that AU films have better transmittance than Ag and AI. The 120 , & Au films have -60% transmittance compared to 70% for ITO. Au films with transmittances reaching 80% were also obtained with a corresponding degradation in resistance. The most important aspect to note is that Au films may have promise as transparent contacts. The resistance and transmittance did ...
