An overview of high-speed plasmonic-organic hybrid (POH) modulators for BPSK and OOK signaling is presented. The optimum length of POH modulators resulting in maximum optical modulation amplitudes (OMA) are discussed.
Limitations of silicon photonics can be overcome by hybrid integration of silicon photonic or plasmonic circuits with organic materials or by photonic multi-chip systems. We give an overview on our recent progress regarding both silicon-organic hybrid (SOH) integration and multi-chip integration enabled by photonic wire bonding.

We report on plasmonic-organic hybrid(POH) phase modulator generating error free (BER<10−10) BPSK signals at 40Gbit/s. In addition, generation and direct detection of 40Gbit/s OOK signals are discussed using POH Mach-Zehnder modulators on the transmitter side.
Silicon-organic hybrid (SOH) integration combines silicon photonic devices with electro-optic organic cladding materials. We demonstrate that SOH modulators can be used to generate advanced modulation formats with high symbol rates at low operating voltages and low energy consumption. Moreover, we show that the SOH approach can be extended to plasmonic waveguide structures, leading to the plasmonic-organic...
Silicon-organic hybrid (SOH) and plasmonic-organic hybrid (POH) integration combines organic electro-optic materials with silicon photonic and plasmonic waveguides. The concept enables fast and power-efficient modulators that support advanced modulation formats such as QPSK and 16QAM.
Silicon photonics offers tremendous potential for inexpensive high-yield photonic-electronic integration by enabling fabless fabrication and joint processing of photonic and electronic circuitry. Besides conventional dielectric waveguides, plasmonic structures can also be efficiently realized on the silicon photonic platform, thereby reducing the device footprint by more than an order of magnitude...
Chip-scale frequency comb sources are likely to become key elements of future terabit/s optical transceiver modules. We demonstrate the viability of Kerr comb generators and modulator-based silicon photonic comb sources for transmission at data rates beyond 1 Tbit/s.
We propose a bidirectional, polarization-independent, recirculating IQ-modulator scheme based on the silicon-organic hybrid (SOH) platform. We demonstrate the viability of the concept by using an SOH Mach-Zehnder modulator, operated at 10 GBd BPSK and 2ASK-2PSK.
We demonstrate generation and transmission of QPSK and 16QAM signals by directly interfacing highly efficient silicon-organic hybrid (SOH) modulators to GTH ports of an FPGA. Peak-to-peak voltages amount to only 0.41 Vpp. Neither digital-to-analog converters (DAC) nor drive amplifiers are required.
Using standard single-ended FPGA outputs with 270 mVpp we demonstrate 10GBd OOK and BPSK transmission by directly driving a low-voltage silicon-organic hybrid (SOH) modulator. The scheme does not require electronic driver amplifiers, which paves the way to energy-efficient photonic-electronic integration.
We demonstrate 16QAM and QPSK modulation at symbol rates of 40 GBd and 45 GBd using a silicon-based IQ modulator. The device enables data rates up to 160 Gbit/s in a single polarization with an estimated energy consumption of 120fJ/bit.
We give an overview on our recent achievements in the field of SOH integration, covering in-device electro-optic coefficients r33 in excess of 200 pm/V, highly efficient Mach-Zehnder modulators, IQ modulators, and modulator-based frequency comb generators
Silicon photonics offers tremendous potential for inexpensive high-yield photonic-electronic integration by enabling fabless fabrication and joint processing of photonic and electronic circuitry. Silicon as an optical material, however, falls short of certain properties that are indispensable for high-performance devices. In particular, bulk silicon does not feature any second-order optical nonlinearity...
