“…To reduce residual IM and increase the bandwidth, the authors designed the bandgap of the phase control region to be much wider than that of the gain region, so the waveguide loss variation induced by the refractive index modulation would be extremely small. The authors presented an array of four lasers in [119]. The modulation efficiency was approximately 5 GHz/V.…”

Photonic systems that transmit and process microwave-frequency analog signals have traditionally been encumbered by relatively large signal distortion and noise. Optical phase modulation (PM) and frequency modulation (FM) are promising techniques that can improve system performance. In this dissertation, I discuss an optical filtering approach to demodulation of PM and FM signals, which does not rely on high frequency electronics, and which scales in linearity with increasing photonic integration. I present an analytical model, filter designs and simulations, and experimental results using planar lightwave circuit (PLC) filters and FM distributed Bragg reflector (DBR) lasers. The linearity of the PM and FM photonic links exceed that of the current state-of-the-art.

“…The 21-Gb/s fiber channel technology has been developed in the storage area network [1]. The 100-Gb/s Ethernet network, based on a four-channel wavelength division multiplexing technology, has been discussed extensively [2][3][4]. For these next-generation networks, low-cost optical transmitter and receiver modules operating over 25-GHz are necessary [5].…”

Summary The TO‐46 header has been commonly used for vertical cavity surface emitting laser (VCSEL) and photodetector package. The high‐frequency characteristics of a TO‐46 header were measured using our special K‐type adaptors and simulated through a three‐dimensional full wave electromagnetic simulator. The measurement and simulation results show the TO‐46 header provides a resonance‐free transmission bandwidth over 40‐GHz and reflection loss below −10‐dB within 31‐GHz, with an ideal 50‐Ω terminal. The 25‐Gb/s and 40‐Gb/s eye diagrams through a TO‐46 header were measured using our measurement setup, and the eye diagrams are clear enough. In addition, the single‐end and differential‐end equivalent circuit models of a TO‐46 header were established and verified. The TO‐46 header provides a low‐cost and high‐speed package solution and can be applied in 21‐Gb/s fiber channel technology and 100‐Gb/s (4 × 25‐Gb/s) Ethernet (100 GbE) network.

“…Multi-wavelength light sources are now key components in DWDM optical transmission systems and are indispensable in future photonic networks. [1] Several types of multi-wavelength laser sources have been reported: the distributed Bragg reflector (DBR) laser array, [2,3] the distributed feedback (DFB) laser array, [4,5] and integrated devices [6] with integrated multimode interference couplers and semiconductor optical amplifier s. [7,8] DFB laser diode (LD) arrays are widely used for their stable and highly reliable single-mode operation. [9,10] However, the grating of the DFB laser is usually fabricated by electron-beam (EB) lithography to form different wavelengths.…”

Four distributed feedback laser array integrated with multimode-interference and semiconductor optical amplifier

et al. 2013

Monolithic integration of four 1.55-μm-range InGaAsP/InP distributed feedback (DFB) lasers using varied ridge width with a 4 × 1-multimode-interference (MMI) optical combiner and a semiconductor optical amplifier (SOA) is demonstrated. The average output power and the threshold current are 1.8 mW and 35 mA, respectively, when the injection current of the SOA is 100 mA, with a side mode suppression ratio (SMSR) exceeding 40 dB. The four channels have a 1-nm average channel spacing and can operate separately or simultaneously.
