A novel design for an integrated passive polarization splitter/converter combination is presented. The device consists of a Mach-Zehnder interferometer with polarization converters in both arms. The device is analyzed using the transfer matrix method and fabricated in InGaAsP-InP. Measurement results show a splitting ratio of approximately 10 dB and a conversion of >90%. This device can be monolithically integrated with passive and active components.

A tolerant single etch-step passive polarization splitter on InP/InGaAsP is designed and fabricated. The device consists of a directional coupler with a wide and a narrow waveguide. Modal birefringence of the third-order modes for transverse electric (TE) and transverse magnetic (TM) polarizations is employed to selectively couple one polarization. Tapering is applied to increase the tolerances. The devices are characterized, and the measurement results show good agreement with the beam-propagation-method simulations: a splitting ratio larger than 95% for a width range of around 100 nm and over a large wavelength range, covering at least the C-band

In this letter, a passive integrated device is presented that enables cost-effective parallel encoding and decoding in a spectral amplitude encoded optical code-division multiple-access transmission system. The device is monolithically integrated in InP-InGaAsP. Simulation and experimental results are given

A compact, ultra short, integrated polarization converter has been fabricated by optical lithography. Length of the converter is 125 μm, and 325 μm including tapers. Conversion efficiency is higher than 95% and loss is less than 1 dB.

Comparison of optical bandwidth of a SOA-MZI using 1x2 input couplers to one with 2x2 input couplers is presented. The simulation shows that wider bandwidth can be obtained in case where 2x2 couplers are used.
