“…The active InP section has a length of 400 μm; refractive index n a = 3.4, and is supplied with a constant current. The passive section with a length of 1500 μm consists of a phase heating section which can be tuned by controlling the heating power P Ph and a Bragg grating which can be tuned by controlling the Bragg heating power P Br [13]. The Bragg grating has a penetration depth of 500 μm.…”

Optical feedback has an impact on the tunability of lasers. We created a model of a tunable distributed Bragg reflector (DBR) laser describing the effect of optical feedback from a constant reflector distance on the wavelength tuning. Theoretical and experimental results are in good agreement. A further discussion of the model sheds light on design rules to reduce the effect of optical feedback on the tuning behavior. We introduced a new parameter called mode loss difference (MLD) as a metric for the feedback tolerance of the tuning behavior. A large MLD indicates higher tolerance of the laser to cavity length variations.

“…To improve the performance, the tuning range of the LO can be expanded, e.g. by using a dual-grating structure and a Y-branch-based thermo-optic switch [29,33,36], to cover the full C-band. The MMI structure can be adjusted to shift the minimal loss band toward the center of the LO tuning range.…”

To fulfill the functionality demands from the fast developing optical networks, a hybrid integration approach allows for combining the advantages of various material platforms. We have established a polymer-based hybrid integration platform (polyboard), which provides flexible optical input/ouptut interfaces (I/Os) that allow robust coupling of indium phosphide (InP)-based active components, passive insertion of thin-film-based

“…Further plans also include the development of a wavelength tunable transmitter for serial operation at 100 Gb/s through the polymer-based integration of an external cavity laser [34] with a high-speed MZM and an InP-DHBT driving circuit. Given its high throughput and flexibility, it is expected that this transmitter will provide a viable solution for the implementation of 100 GbE interfaces in the OCS domains of next generation DCNs.…”

We demonstrate a 2 × 100 Gb/s transmitter and a 4 × 100 Gb/s receiver as the key components for multi-100-GbE and 400-GbE optical interfaces in future intradata center networks. Compared to other approaches, the two devices can provide significant advantages in terms of number of components, simplicity, footprint, and cost, as they are capable of serial operation with nonreturn-to-zero on-off keying format directly at 100 Gb/s. The transmitter is based on the monolithic integration of a multimode interference coupler with two Mach-Zehnder modulators on an electro-optic polymer chip, and the hybrid integration of this chip with an InP laser diode and two multiplexing and driving circuits. The receiver on the other hand is based on the hybrid integration of a quad array of InP photodiodes with two demultiplexing circuits. Combining the two devices, we evaluate their transmission performance over standard single-mode fibers without dispersion compensation and achieve a BER of 10 −10 after 1000 m and a BER below 10 −8 after 1625 m at 2 × 80 Gb/s, as well as a BER below 10 −7 after 1000 m at 2 × 100 Gb/s. Future plans including the development of tunable 100 GbE interfaces for optical circuitswitched domains inside data center networks are also discussed.
