“…The MCEF of the 30-μm-long device is higher than that of the 60-μm-long device due to the small active region. However, the value of 7.9 GHz/mA 1/2 for the 30-μm-long device was slightly smaller than the 11 GHz/mA 1/2 of the previously reported membrane DFB laser with the same active region volume of 0.9 μm 3 [43]. The reason for this is low differential gain due to the twice-higher threshold current density of 1.4 kA/cm 2 than that (700 A/cm 2 ) of the membrane DFB laser.…”

“…At this bias condition, the energy cost of the device is estimated to be 980 fJ/bit which is not close to the required 100 fJ/bit. The reason for this is higher bias current compared with previous work [43] due to the noisy signal pattern.…”

“…Integration of the membrane DFB laser with a p-i-n-photodiode (PIN-PD) was also demonstrated [41]. Recently, high-speed direct modulation characteristics of a membrane DFB laser with a modulation current efficiency of 9.9 GHz/mA 1/2 were reported [42], and low bias current 10 Gb/s data transmission with a bit-error-rate (BER) of 1 × 10 −9 was achieved using an optical amplifier [43].…”

To advance on-chip optical interconnections, membrane distributed-reflector (DR) lasers with low threshold current and high-efficiency operation at one side output were realized. First, a membrane distributed Bragg reflector (DBR) laser with 80-µm-long active section and 50-µm-long DBR section was fabricated to clarify the DBR reflectivity. An external differential quantum efficiency of 35% for the output from the front facet was obtained, and the DBR reflectivity was estimated to be 75%. Next, a membrane DR laser with 61-µm-long distributed feedback section and 50-µm-long DBR section was fabricated. A threshold current of 0.48 mA, external differential quantum efficiency from the front side waveguide of 26%, and light output ratio from the front to the rear sides of 13 were obtained. The lasing spectrum showed a single-mode operation with a side-mode suppression-ratio (SMSR) of 40 dB. Finally, small-signal direct modulation was carried out and a modulation current efficiency factor of 7.9 GHz/mA 1/2 and 7 GHz/mA 1/2 were, respectively, obtained for the 30-µm-long and 61-µm-long devices.

“…Because the measurements were performed using on-chip p-i-n PD, f 3dB represents bandwidth of the optical link. Modulation efficiencies of 10.8 GHz/mA 1/2 and 7.6 GHz/mA 1/2 were obtained for f 3dB and f r , respectively; the latter was smaller than that obtained in our previous work (11 GHz/mA 1/2 ) [52]. However, the active volume of the DFB laser in this work was 2.16 μm 3 , which was larger than the previous one (0.9 μm 3 ).…”

On-chip optical interconnection is a promising technology for wiring future large-scale integrated circuits, as a means to mitigate the considerable power dissipation of traditional wiring layers. Here, we fabricate an integrated optical link using a membrane distributed-feedback (DFB) laser and a p-i-n photodiode (PD) in a butt-jointed built-in coupling geometry. The optical link is formed on a Si substrate by benzocyclobutene bonding. The integrated DFB laser shows a low-threshold current of 0.48 mA. Light transmission between the DFB laser and the p-i-n PD is confirmed with static measurements of the optical link. The optical link has a 3-dB bandwidth of 11.3 GHz at a 2.73 mA DFB laser bias current and a -3 V p-i-n PD bias voltage. A data transmission experiment of the optical link is performed, using a nonreturn to zero, pseudorandom-bit-sequence with a word length of 2 31 -1 signals. With a DFB laser bias current of 2.5 mA, 10 Gbit/s data transmission with a bit-error-rate of 6 × 10 -7 is successfully achieved.

During the cyclones and floods, all through the nation, the telecommunication network services were the most hit, leaving numerous individuals stripped from the ability to contact their precious ones. This paper is to demonstrate potential communications during such power blackouts. The double clad fiber is used for optically powering, transmitting and receiving the data to and from the remote antenna units by the Bidirectional method. The RoF multiband signals such as baseband, millimeter wave, and microwave, are transmitted and received bidirectionally by the single mode core, and power in outer clad to the Remote Antenna Unit. By the proposed RoF link transmission of 1 Gbps over a 100-Km DCF with an optical power of about12.0 W is achieved.bidirectional communication, double clad fibers (DCFs), power over fiber (PoF), radio over fiber (RoF), remote antenna units (RAUs) | EXPERIMENTAL ARRANGEMENT
