“…For example, OptiSpice [5,6] is an excellent tool that correctly captures transient effects as well as amplitude and phase effects, but is written as proprietary standalone software suite. This is also true of [11,[14][15][16]. Lumerical's INTERCONNECT® [10] is another excellent tool that that is written as proprietary standalone software.…”

“…Several simulation tools or individual models have been presented [4][5][6][7][8][9][10][11][12][13][14][15][16]. Only some of these [4][5][6][7]10,11,[14][15][16] are able to properly capture transient behavior of all photonics components, handle frequency shifts and model both amplitude and phase effects (usually while removing the optical carrier for faster simulation time) and interference. Of this subset, all are written as standalone software and are therefore difficult to adapt into existing circuit design and layout infrastructures -especially with the transistor Spice or Spectre models provided in standard process design kits (PDKs).…”

Electro-optical co-simulation for integrated CMOS photonic circuits with VerilogA

et al. 2015

We present a Cadence toolkit library written in VerilogA for simulation of electro-optical systems. We have identified and described a set of fundamental photonic components at the physical level such that characteristics of composite devices (e.g. ring modulators) are created organically - by simple instantiation of fundamental primitives. Both the amplitude and phase of optical signals as well as optical-electrical interactions are simulated. We show that the results match other simulations and analytic solutions that have previously been compared to theory for both simple devices, such as ring resonators, and more complicated devices and systems such as single-sideband modulators, WDM links and Pound Drever Hall Locking loops. We also illustrate the capability of such toolkit for co-simulation with electronic circuits, which is a key enabler of the electro-optic system development and verification.

“…Note that the current level of integration has been reached by micro-electronics by 1969 -during the infancy of the first electronic circuit analysis programs [3]. Remarkably, now we recapture those times once again, living in the beginnings of commercially available photonic circuit simulators [4][5][6][7][8][9].…”

We present our approach towards an automated design framework for integrated photonics and optoelectronics, based on the experience of developing VPIcomponentMaker Photonic Circuits. We show that design tasks imposed by large-scale integrated photonics require introducing new "functional" types of model parameters and extending the hierarchical design approach with advanced parameter scripting capabilities. We discuss the requirements imposed by the need for seamless integration between circuit-level and device-level simulators, and illustrate our approach for the combination of VPIcomponentMaker Photonic Circuits and VPImodeDesigner. We show that accurate and scalable circuit-level modeling of large-scale photonic integrated circuits requires combination of several frequency-and time-domain simulation techniques (scattering-matrix assembly, transmission-line models, FIR and IIR digital filters, etc) within the same circuit simulation. We extend the scattering-matrix assembly approach for modeling linear electronic circuits, and motivate it being a viable alternative to the traditional modified nodal analysis approach employed in SPICE-like electronic circuit simulators. Further, we present our approach to support process design kits (PDK) for generic foundries of integrated photonics. It is based on the PDAFlow API which is designed to link different photonic simulation and design automation tools. In particular, it allows design and optimization of photonic circuits for a selected foundry with VPIcomponentMaker Photonic Circuits, and their subsequent export to PhoeniX OptoDesigner for layout verification and GDSII mask generation.

“…This can be undesirable if the temperature as well as the injection current has to be precisely chosen to match certain wavelength and optical output power conditions at the same time. Considering applications where the DFB lasers are used as sources in integrated photonic circuits [7], with monolithically integrated amplifiers or in laser chip arrays [8] a screening prior to integration is hardly possible and the yield loss of more complex systems or arrays due to the spectral behaviour of individual emitters may make their fabrication uneconomical. In contrast, a common design approach in DFB lasers is to apply anti‐reflection (AR) coatings to both facets and introduce a quarter‐wave phase shift within the cavity to guarantee single‐mode emission as well as a wide mode‐hop‐free range of operation conditions [9, 10].…”

A distributed feedback laser with integrated quarter‐wave phase shift and more than 100 mW optical output power at an emission wavelength of 780 nm is presented. The laser provides mode‐hop‐free tuning over a wide range of injections currents and operating temperatures by design and can serve as an enabling component for more complex systems such as chips with additional monolithically integrated amplifiers, chip arrays and sources for hybrid integrated photonic circuits.
